Well
When one of the contacts that i have enabled to auto-accept requests sends me a file, the chat window with that contact pops up and accepts the file transfer.
It probably does this to use the keyb_event api to press the accept keys.
Maybe you can do something to check if the window is minimized and if is, accept the transfer and minimize the window...

Its suppost to put the previous window back into focus.

It works for me but when playing a game , The game comes back up but not in focus and they buttons dont work and I die
