LiveCode Forums.

Now that LiveCode 4.5 has been launched, I'd like to offically announce that we've launched PowerDebug for LiveCode and MetaCard, an upgrade for the built-in debugger/variable watcher/runtime error stacks. There's a trial version on revOnline that is fully functional but will present annoying nag screens (launching your browser) at random intervals to encourage you to buy the unrestricted version (at a special launch sale price). There's also a walkthrough of most of the features at

Yes, it will allow you to debug preOpenCard and resize handlers that are otherwise out of reach. More features than I would care to take up bandwidth listing here, including a nifty ExplainError() function you can call from the messagebox to help demystify those cryptic error codes. Works with/without tRev, so you can do both debugging and decoding. Just about everything you could ask for in an xtalk debugger.

...and (by way of a preannouncement) soon you'll be able to trigger a virtual breakpoint from a specified message issued by any script: something calling DisplayAboutBox but you don't know where? Just set a virtual breakpoint for that message and you'll be placed in the debugger with the context of the caller.
