Rhino crashing when saving .png

Rhino won’t save .png files with transparency when done from a script and doing this manually I actually encountered a crash trying to save a .png file.
The crash report is on my desktop and is 62 megs where do I send these files to? No crash report or any warning was issued when this happened Rhino just vaporized on trying to save.
I can’t go back to V5 to test the above as I only have v6 on this newer computer.
Please fix the transparency bug I can’t do 360 frames manually and another glitch is that occasionally even if transparency is checked and saved manually Rhino still doesn’t save the image with transparency.

Hi RM - please upload the file to
