That is the touchscreen behaviour. Are you running W10 in Tablet Mode (start menu and applications always using the full screen)?
</div>


<div>
Please try with another <b>USB</b> mouse and let us know the result.

I am using a Wacom pen tablet. The stupid win 10 thinks I have a touch screen. How can I correct it?
</div>


<div>
<a href="http://www.thewindowsclub.com/disable-touch-screen-windows-10" rel="ugc">http://www.thewindowsclub.com/disable-touch-screen-windows-10</a> describes that all you need to do is go into Device Manager and disable the Human Interface Device (HID) driver for the touchpad.

Qlemo: &quot;Are you running W10 in Tablet Mode? NO <br />
Ramin: &quot;Please try with another USB mouse and let us know the result. GOT NO MOUSE. ANOTHER WACOM: SAME THING<br />
Qlemo: &quot;&nbsp;go into Device Manager and disable the Human Interface Device (HID) driver for the touchpad. DONE. HAD NO EFFECT<br />
Ramin: &nbsp;&quot;Uncheck &nbsp;Enable press and hold for right-clicking.&quot; &nbsp;DONE. HAD NO EFFECT.<br />
<br />
It looks to me to be a settings problem somewhere - but I can't figure out where. <br />
Also: when I left click and pull acroos a text to highligt it, &quot;the opposite&quot; happens: the marker disappears during the pull, and nothing is highligted. That doesn't make sense to me at all. (all of this: only in Chrome).

Thank you, Ramin!<br />
This took care of most of the strange behavior, but not all. The most strange is still here:<br />
When I try to mark a string of words by left-click-draw, the marker disappears while left mouse button is down and nothing is marked. <b>UNLESS </b>(!!!) I first double-click in an open Word document and then go to the chrome window; then the mark-up works once.<br />
Same thing done vertically just scrolls the document. <b>UNLESS </b>(!!!) I first double-click in an open Word document and then go to the chrome window; then the mark-up works once.<br />
My Wacom pen tablet is correctly configured in its driver I the control panel. One button is right click, the other is double click.<br />
Any clue?<br />
ONE MORE INFO:<br />
If I place the cursor in a text (still in Chrome), keep shift key down and use right-arrow-key, the text gets marked up as I want, In this weird problem one gets happy if <i><i>anything </i></i>works...
</div>


<div>
As a <b>workaround</b> for that issue, &nbsp;Disable 'Use Hardware acceleration in Chrome settings.<br />
<br />
Chrome &gt;&gt;&nbsp;Settings &gt;&gt;&nbsp;Advanced &gt;&gt;&nbsp;System. In the System section, uncheck the box next to <b>Use hardware acceleration when available </b>and restart Google Chrome.
</div>


<div>
Go to Control Panel &gt;&nbsp; Pen and Touch &gt;&nbsp;Flicks and &nbsp;disable Use flicks to perform common actions. (if there is such option).
</div>


<div>
Please type the below command in Chrome address bar, hit the enter and let it to update then restart chrome and test.<br />
<b>chrome://settings/help</b>

<div>
Thanx - I'll continue tomorrow - it's late night here now.

Thanx - chrome://settings/help &nbsp;gave no change.

I don't know the correct name for this blue thing popping up all the time. If I knew that, I could google it.<br />
Windows or Chrome must think that I am having a touch-screen. But I don't. I have a Wacom pen &amp;&nbsp;tablet. And I want to continue using it as a refined mouse and not acting as a fat finger on a touch screen.

Thanx!<br />
Windows Ink is already unchecked.<br />
The other one I shall try when I get home. (Deep down in my memory I feel I have seen that advice before. I think it is good!)<br />
Thanx again.<br />

<div>
Unbelievable, Ramin! Literally unbelievable, but nevertheless true.<br />
Such a simple solution to such a tricky problem!<br />
Thank you Ramin - and thank you Qlemo - it might be the combination of all the solutions that finally broke the camel's back.<br />
At any rate: I got my old Chrome back.<br />
Happy holiday for all of you1<br />

When I make a long left click, a white circle appears on the screen and the context menu appears when I release.<br />
What a clever way to fake a right click if you can't make a right click.<br />
And how annoying it is when you don't want it!<br />
Can anyone please tell me how to turn it off?

Windows 10 is a personal computer operating system featuring the "universal application architecture" (UAP); apps can be designed to run across multiple devices with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and HoloLens. Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.
