Synfig quitting when changing blend modes

I’m trying to change blending modes on layers that I created and my computer keeps crashing. I was trying to do a “straight onto” mask for bra straps, but the file cannot handle it. I tried changing the rendering mode and also tried opening a new file and trying it. It works fine in a fresh file. Can I possibly have to much info in my file and “choke” the program? Any one else have a problem like this?

Thanks in advance for any help. Let me know if you need more info.

Thx!
Stephen:)

Hi Stephen, please inform about the OS, architecture and Synfig version.
If you can provide sample file to reproduce the problem it would help.
Thanks!
