I have benefitted greatly from BugTrapper. We haven't handed the agent to any clients, yet -- in-house is where we use it (mostly on NT). This handy tool keeps me from having to install a debugger on many systems I test. Also, it prevents the need for remote debugging when you want to see what's going on inside a GUI drawing section of the code. One great example was that I had a thread-locking problem. I knew it was there, but had no idea how it was happening. (It involved a few re-entered message loops and 3 threads.)The debugger wasn't giving me enough information (the stack doesn't trace between threads), so I set up a BugTrapper trace file. Now, I could step through the execution of multiple threads as though they were one thread (a great boon). After a little looking, I located the lockup and fixed it! Anyway, trying out BugTrapper is the best way to find out if it will be useful in your own work environment. Joh
