Ok, the first thing I would do is that the known good firmware (firm0309.lgo)
loads with all of the tools that you are interested in.
The next thing is that any custom image you put in the RCX may or may not
respond to the delelte firmware command.
I'll bet that your image file has a bug and the RCX is hanging - like it's supposed
to.
When you get frustrated with WebCompilers, give pbForth a try :-)
