"input in flex scanner failed"

I try to swallow a simple FvwmScript label into my ButtonBar, but that’s the error I get.
What does it mean?

That doesn’t really sound like an FVWM error to me…

I’m not sure, but I figured out the solution. The script’s filename has to be the same as the application name. That’s strange, but now it works well :smiley:
