I'm trying to set up various scenes in MyDMX and would like to use numbers for shortcuts. I tried setting it up with numbers but it wouldn't work. Letters work fine, but numbers didn't. Can it be done?

I have used numbers without any problems. I use the numbers along the top of the main keyboard, not on the numeric pad. try this, it may be the problem.

Also check you NumLock & Scroll lock keys, just in case they are switched on/off
