Random "mouse-clicking" or random toggle (can't find a better title)
I started having this problem yesterday:
Whenever I am scrolling or just typing inside a MS-Word-2010 or PDF document, it's like someone is clicking with the mouse outside the window. The window menu is greyed out, and the blinking mouse cursor disappears.
In order to continue scrolling or typing, I have to click back on that window.
Sometimes it happens even while I'm typing, then I discover that some of my typing doesn't appear in the document and I have to click on the document again in order to bring back the mouse cursor into the document
I use a wireless mouse but it also happens when I turn it off and use my laptop's touchpad
2 days ago I installed a Java update and NET framework updates.
I thought about preforming a system restore but I thought maybe someone here has a clue about this problem. I had trouble searching the net for this issue, as I'm having a difficult time describing it
