Some applications run in the background as well as in the foreground. &nbsp;I'm not sure WhatApp is one. &nbsp;Is there a taskbar icon? &nbsp;If not, then the app is not running in the foreground and can probably be closed using Task Manager.<br><br>If there is a taskbar icon, it may be the application was moved or spawned off-screen. &nbsp;In that case, right-click on the taskbar icon, select "Move", then use the arrow keys to move it a little. &nbsp;After that it will snap to the mouse pointer, so you can just move the mouse and the window will appear wherever the mouse is.

I don't think this is a WhatsApp issue. It seems like a Windows issue. I¨'ve seen this several times... Usually killing all processes or reboot help. Sometimes the reinstallation is needed.

Paul, on your comments, there is a taskbar icon and it is indicating that it is running. &nbsp;I followed your suggestion as i also thought it was off of the screen, but there is no &quot;move&quot; selection. &nbsp;<br />
On Hello's comments I did reboot the computer, killed all processes, Uninstalled Whatsapp, and even used a program called &nbsp;&quot;registarHomev8 to remove (hopefully) all instances from the registry. I then downloaded a fresh copy of the installation file and re-installed but it still acts the same. &nbsp;I am going to try another thing I just thought of now, and that is to set up a new account and see if it will run on that.

Setting up another account fixed the issue. &nbsp;Thanks you both for helping me with this issue

Instant messaging (IM) is a type of online chat that offers real-time text transmission over the Internet. A LAN messenger operates in a similar way over a local area network. More advanced instant messaging can add file transfer, clickable hyperlinks, Voice over IP, or video chat. Non-IM types of chat include multicast transmission, usually referred to as "chat rooms". Depending on the IM protocol, the technical architecture can be peer-to-peer (direct point-to-point transmission) or client-server (a central server retransmits messages from the sender to the communication device).

Chat / IM

A social networking service is a platform to build social networks or relations among people who share similar interests, activities, backgrounds or real-life connections. A social network service consists of a representation of each user (often a profile), his or her social links, and a variety of additional services such as career services. Social network sites are web-based services that allow individuals to create a public profile, create a list of users with whom to share connections, and view and cross the connections within the system. Social networking sites allow users to share ideas, pictures, posts, activities, events, and interests with people in their network. Other popular services include Google+, LinkedIn, Instagram, Reddit, Pinterest, Vine and Tumblr.
