Hi,

Yes, I've installed both ruby and wxruby. The problem I have is that
if the app fails to start, it is sometimes due to syntax errors and
sometimes due to runtime errors (e.g. a nil member variable, etc.).
Without a DOS/Command window, firstly, I've no idea if it's a syntax
error, secondly, even if it does start, I can't use 'print' to print
out debugging statements to help me find out where I got to and what
went wrong (OK, I can open an auxilliary window and write to that, but
I could lose that window if the app dies). How do you experts debug
wxruby apps? Any help would be appreciated.

Thanks again,

RC
