I have posted a Debian bug about the problem I have had with VMWare and the Awesome window-manager.
Turns out that the shortcuts only works when the mouse is not over the VMWare virtual screen. That means it is less annoying than I first expect, but still annoying nonetheless.
JD was nice in installing VMWare to diagnose the problem. I know some developer who would not have bothered to install such a big piece of proprietary software to debug a problem which probably annoys just one person, me, in the whole world.
VMWare is a critically important tool for us at work. I'm not gonna get into details of why and how we use it. It will be better left as the subject of another post. I don't feel I need to justify the bug I posted, but it is very important for me that I'm able to use this tool efficiently in my development environment.
