I noticed this about a 4 days ago...
If I went to download a file, it wouldn't let me save it - it was grayed out.
Last night, I was trying to write a data DVD w/some files on it, and I couldn't drag/drop files into the window of CDBurnerXP. It also wouldn't let me add them, thru the program menu.
I also discovered that the drag/copy function wouldn't work, between folders.
Cut/paste works fine.
Also, the Windows 7 taskbar at the bottom of the screen is non-functional at bootup, but if I go to task manager and quit explorer.exe and then run it again it comes back.
Actually, just opening Task Manager brings it back.
Browser windows for all programs are also acting funny - not being able to close them and such.
If I need to fill out a form online, I can't select from a dropdown menu.
I did a Malware and MS Security scan, in safe mode, and ran scf/scannow in admin mode, w/no joy.
Any clues? I haven't found anything about this thru Googling.
Thanks in advance!
