There are times when the system doesn't respond to mouse clicks on task bar, and most noticeably when gMail is being read on Chrome.<br />
I can get a response from clicks if I ctrl-alt-del &nbsp;and start Task Manager. &nbsp;Something about that procedure seems to get the computer responding again.<br />
No problems with keyboard. &nbsp;If clicking on gmail in Chrome doesn't work, I can still Alt-Tab to other programs.<br />
<br />
Can't figure out what's damaged.<br />
<br />
All MS updates have been installed.<br />
I ran AdwCleaner and RogueKiller, which found some things, including a Chrome extension that I removed.<br />
MalwareBytes and Microsoft Security Essentials are installed.<br />
<br />
Thanks.

Windows 7 won't respond to mouse clicks until Task Manager is started.

Windows 7 is an operating system from Microsoft. Features include multi-touch support, a redesigned Windows Shell with a new taskbar, referred to as the Superbar, a home networking system called HomeGroup, and performance improvements.

Web browsers are applications used primarily to display documents, files and media from the Internet, identified by a Uniform Resource Identifier (URI) that can be a page, image, video or other file. Some browsers require the use of add-ons or extensions to safely render the information they receive; others have systems built into them to perform the same functions.

Spyware is software that aims to gather information about a person or organization without their knowledge and that may send such information to another entity without the consumer's consent, or that asserts control over a computer without the consumer's knowledge; it has also come to include programs that engage in various kinds of electronic fraud. Anti-spyware is software that removes or blocks that software; some common vendors include Malwarebytes, McAfee, Spybot-Search and Destroy, Ad-Aware and BitDefender.
