Bitcomet kicks back to Desktop when a download finishes..

Hi everyone,

I'm posting today because I'm experiencing a very annoying issue regarding my client. When bitcomet finishes downloading a file, and when i'm, for example, playing a game, it systematically kicks back to desktop.

I have no idea what can cause this issue, or even if others are experiencing it. Please help me!

Here are the necessary informations :

1) Bitcomet 1.37 (64-bit)

2) Adsl 8 mb.

3) Have a router.

5) Windows 7 64 bit, windows integrated firewall, and avast antivirus.
