My plugin sometimes crashes on exit

Hi

i developped a 8bf plugin for Photosop™ and when i quit the plugin, i have sometimes issues:

1) the plugin window freezes and the plugin run forever.

2) the plugin crashes PS directly.

it happens more often when i've had some heavy computations

in the destructors, i only call delete if i've created some 'new' objects and that's all.

I almost feel like it would be better if i didn't include these deletes...

thanks for any answer

Jeff
