Comment 60 for bug 1292290

I have the same ussie. I'm using Alt + Enter to maximize. It works until reboot. In next run shortcut is erased. Happens only with maximize function as for topicstarter.

It happens in "us" keyboard layout. I have quite standard system with standard package sources. Bug is stable reproducible.
