I think I may go back to V3 for awhile......
Brought up L4 and was told there was a revision, so I waited while it installed. I know there was a problem re dragging things into the shortcut area, so I supposed the revision was a fix for that. (How do you determine what release you're running?)
First thing I tried was clicking the mouse wheel to see if it was fixed - it wasn't. Then I was playing around, just scrolling my NASB using the scroll bar with my Logitech trackball (line at a time). All of a sudden, everything froze - scroll bars wouldn't work and neither would anything else. Went back to FireFox and after a moment nothing worked there either. Finally used <CTL><SHIFT><ESC> to bring up Task Mgr and killed L4. Everything started working again.
Although L4 had mentioned it was going to do some indexing and though I had several programs open, there didn't seem to be any load at the system at the time. Programs running were FF, Thunderbird, iTunes, Live Messenger, AVG (free) and Compupic.
