Sometimes when i close a program the window disappears, but if i try to reopen the program, windows says that it's already running. So I open task manager and try kill the process but it just won't do it. It doesn't even come up with an error message, it says do you really want to end this task, and I click yes and it acts as if it's killed it. But the process is clearly still there and just wont end unless I restart the computer.
This mostly happens with uTorrent, but sometimes others, so I don't know if its a problem with their program or with windows.
Any help would be much appreciated.
Im running windows vista home premium btw.
