My PC keeps deselecting the window I am working on

[angelgirl.0070]

I have read about this topic on the website and I am sure that it happens because of my TP-link wireless adapter. The simple solution would be to stop the adapter or shut it off but I can't do that. I need to use the adapter in order to connect to the internet since I can't use a cable on this PC. How can I stop my PC from deselecting the window without getting rid of the TP-link wireless adapter? Thanks in advance!

Are you sure it's adapter's fault ? Can't see a connection between them. Have you tried it ?
