So far, I've stuck to MsgBox and ConsoleWrite to debug scripts (+some SciTE Syntax Checks), but looking for something a little better.
It seems both Heron's Debugger: http://www.autoitscript.com/forum/index.php?showtopic=103142
and "Another Debugger for Autoit"
have been abandoned. I'm curious what tools forum members are using to debug scripts?
