Windows 10: Active window randomly loses focus

On the new computer I got about 2 months ago, the window I am using sometimes loses focus at random. I can be typing something and then suddenly it will stop accepting my input and make a sound, or I could be scrolling and suddenly it would stop. I can't even play Minecraft for 15 minutes without the game going ahead and pausing by itself because of this. And before you say it's a Windows issue, this never happened on the computer I'm typing this on (which is the one I did all my other posts on), meaning it's something on the computer.
Sometimes, the culprit is obvious (and it's McAfee), but most of the time this happens, it's completely out of the blue. This is so annoying. What can I do?

Windows lose focus

When my Cingular 8125 is connected to my Vista Ultimate 64-bit machine, opened windows randomly lose focus. Whatever application is active will suddenly go inactive, as if I [alt][tab]'d off it. The issue immediately clears up as soon as I disconnect the
pocket pc. The issue is annoying as I will be typing in some text control, then the app loses focus, then it regains focus and all text in the field automatically highlights and is overwritten with the next keystroke. Any ideas?



BTW, the version of Window Mobile Device Center is current.

 

Windows loses focus every 3-5 seconds

This focus issue is making it nearly impossible to type anything continually. Windows loses focus every 3-5 seconds, pausing and not typing what I've typed. I can't live with this- any suggestions?

 

Windows lose focus

Absolutely! Even when trying to navigate to applications from the Start button, it will lose focus and close. I have to be very quick to open up an app before the Start menu closes.



With only Mobile Center open, I can watch it go "active" / "inactive" / "active" / "inactive", etc. I'm thinking it will have to do with the way windows is polling the device for changes.
