Not only is the simkey not working, it was not even coded for!
Also the simkey editor should not allow "send methods" or any repeat stuff.
Test in 2.21 Beta 46
When the profile is activated, the on activation simkeys are not sent, nor is the process launched (although the log suggests it is).
Whe editing the command to run, the apply button does not highlight (need to change something else too to enabe apply).
The log should say WHAT command is being executed, and what simkey is being executed.
