After leaving LimeWire 3.9.1 beta (on sun's java 1.4.2_03 in linux) up for 10 minutes acting as an Ultrapeer but minimized and going to restore it, I noticed that it doesn't even redraw the window anymore and I have to mouse over the window to redraw the part of the window where I moved my mouse. When this happens, the "Monitor" tab when clicked no longer switches to the tab while the "Search," "Connections," and "Library" tab can be switched to fine. Also the menu bar doesn't redraw at all unless a menu is clicked or unless I minimize the window and restore it a few times. When I exit LimeWire then reload it, everything works again, then the redrawing issue repeats after I leave it minimized for a few minutes. This doesn't seem to happen at all in LimeWire 3.8.6.
