TRON TOFF ahh the old days, in Netscape?

Hi all, a bit new to Java and often I have questions pop into my head as you can imagine

I have to limit myself as Im sure most have been asked somewhere before and I'll come across them as my education progresses.

For some reason I have always struggled with debugging and I suppose its going to be one of those subjects like documentation, that no one really enjoys - I come from a programming background from years ago. One of the things I keep wanting to have is something similar to Tron and Troff. or Trace on and Trace off. In those days you would use this to trace the route of the program and you could step it line by line. Now using Netscape Im wishing I had a similar feature.

I have a problem at the moment where a part of my GUI is not updating, it does when I do one thing but not when I do another, it would be helpful if I could trace the route through listing the methods the program invokes as it invokes them. I could then see why its not updating.

Cheers folks,

Phil
