G27 losing ffb when minimized

[=WOLF=[NO]]

I am visiting a friend while working, and I got him to buy a G27 , playseat, and joystick.

After a while, we figured I could use my computer for lfs on his rig, since his pc is used on the tv.

Now over to the issue:
I start up my computer, start lfs, and everything works fine.
If I minimize, get a skype chat/call, or any other backround task, the ffb is gone.
restarting lfs or reconnecting the g27 will not help, only a reboot will solve it

Does anyone have amy ideas how to fix the problem?
The wheel works fine on his computer.....
