Gnome

[Jeffrey Ross]

I just starting moving a lot of files on to a USB hard disk, which 
consists of deleting about 20 GB of data and then putting about 15GB of 
data back on.  This appears to be working fine, however....

Once I started the data copies (two of them) and the "empty trash" 
commands all at the same time I noticed that I lost the ability to 
manipulate the windows on the screen.  I lost the border around the 
windows, I can't resize, minimize, maximize etc.

Suggestions?

Thanks, Jeff
