I noticed that in P6 (original release, SR1 and SR2), that while a python script is running, certain Poser confirmation dialogs are not presented to the user. Instead they seem to be redirected to the python console window and return an 'OK' automatically.

For instance, if you lower the ending frame in the animation window, Poser will present a confirmation dialog asking:
"Are you sure you want to delete some of your frames?"
And you can select 'Cancel' or 'OK'.

Attached is a simple python script that does (almost) nothing. Try the above test, then run this script and try again. Then close the script and try again.

Any thoughts or ideas?
