Here's my problem:

Whenever I start dowloading files, and then leave my computer for a long period of time(sleep, go to school, etc) and leave Limewire minimized in the system tray, when I come home and move the cursor towards the Limewire icon in the system tray, it just dissappears. I then proceed to click on the Limwire Desktop icon and when Limewire loads it shows that none of my downloads have made any progress. Most of the downloads are either tv shows or movies, and they are now almost impossible to download without staying at my computer the whole time. Anyone know why this is happening? Any help would be greatly appreciated. Thanks.
