I couldn't get the LiveView in chdkptp to work while browsing files worked. Is that the kind of problem you mean?
I can't switch to rec mode though and the console plays dumb when I enter lua commands.
But I guess those are entirely different problems that don't have to do with anything you meant.
The "rec" button works and I can see the live image in chdkptp on Windows 7.
Are we talking about different programs? I don't see a debug tab(see attachment).
Here's a quickdump from rec mode:
