This is an urgent problem!

This is the full code of my main.cpp (minus stuff that wouldn't be good out in public).

Here's the situation: Only if the user does not run my plugin (or the dialog isn't restored in the layout during startup), C4D is guaranteed to crash on exit Windows/MacOS R8.2-R9.6 confirmed.

I've narrowed this down to one line (marked below) : the SNHookClass::Register() method. Could it be that the plugin_id in Register() must be different that the main plugin id (doesn't seem to make a difference)? If you see anything that seems out of place otherwise, please do not hesitate to mention it as well.

After all of that, I traced the problem to the instantiation of the main dialog. If it is only done in CommandData::Execute() and CommandData::RestoreLayout(), then the crash-on-exit disappears.
