Complete Crash?

What can I do to debug a plugin when Sketchup just crashes and closes without any message or chance to see a problem on the Ruby console?
My guess is that it's having problems colouring some faces, but it really shouldn't.

hi

are you running it from the 'plugins folder' or from Ruby Console.

I turn off 'ruby' [the plugins folder] and run the new script from console either by copy pasting all [mac only] or line feeding.

that eliminates clashes with other plugins.

if all works fine I turn Plugins back 'on' and retest.

OK, I've narrowed it down a bit and this seems to be the line that makes it crash:

savePath = UI.savepanel("Save results file",model.path,"Sunlight analysis.csv")

If I Process.exit() just before that, SU stays open. Otherwise it crashes. Weirdly, though, not always. On a few occasions it survives. This is on Windows Vista: never had this problem on Mac in a whole lot of testing.

OK...it doesn't crash if just before showing the savepanel I put a line of code to show a simple messagebox: then the savepanel shows. Although the messagebox is nowhere to be seen.

Then I tried this code:

			if UI.messagebox("Save results to file?", MB_YESNO) == 6
				savePath = UI.savepanel("Save results file",model.path,"Sunlight analysis.csv")
				# If the user doesn't press cancel;
				if savePath
					outfile = File.new(savePath, "w")
					outfile.write(allResults)
					outfile.close()
				end
			end

Now when the execution reaches this point SU suddenly switches program, i.e. as if someone had pressed Alt+Tab. It's still there, but I have to reopen it. And the messagebox still isn't anywhere, hence neither is the savepanel. I just seem to have gotten the UI very confused in general.
