You do not have to sign the ide. You can use FpDebug as external 
debugger, then you only have to sigh the FpDebug executable itself.

Strange, debugging threads works fine. At least on Linux and OS/X. There 
were some memory-leaks in the show-threads window, though. I've asked 
you to look at it.

Everyone who wants to help improving the debugger, should stop working 
with gdb and install fpdebug. And start filling bugs. Fpdebug is already 
better in many aspects then gdb, only now and then I have to switch back 
to gdb.
