Control & Alt keys not working in 0.60 beta

[Arkaitz Bitorika]

Hello everybody,

I just upgraded from Blackbox 0.51 to the 0.60 beta, and everything seems
alright except that the key combinations Control+arrow for workspaces and
Alt+Tab for windows are not working any more. I have tried changing them
in the .blackboxrc file, but it doesn't work. Does anybody have any idea
of what can be going on? 
I am running Slackware 7 with Linux 2.2.14.

Cheers,

Arkaitz.
