I was one of those who signed up for the Windows Insider program leading up to the general release of Windows 10. This is on a Dell Inspiron 1720 laptop that had Windows Vista Home Premium (32-bit). At the end of the preview period the machine has upgraded to Window 10 Pro 32-bit.
I am having a repeated problem that I find very weird. My mousepad works just fine and when I click on the Win10 Start button or icons in the quick-launch toolbar the start menu appears or the program in question launches, but that's where normal responsiveness ends. If I select an item from the start menu or try to click on either the window for a program that's started, or a tab on a web browser window if that's one of the programs I get absolutely no response - nada.
At the moment I'm Firefox, File Explorer, and Microsoft Edge - all of which fired right up - but none will respond to the mouse. This is not a one-time incident and very often shutting down, completely, and restarting results in no change in behavior.
I am wondering if anyone else is encountering anything similar? This is a very weird behavior and I never even experienced this in the preview builds. I can't for the life of me figure out what's happening here.
