I'm on win7 64bit. Downloaded Purr Data today.
I uploaded one patch which has an error. Because of my settings it adresses iemgui directly, so it isn't found in Purr Data.
The console told me room_sim_2d .... couldn't create.
When I go into that patch and try to delete the knobs, I get a crash. I have to close the nw.exes in the task manager of win7. The running pd process can't be killed at all.
You'll find the patch here (download the folder "crash" and start it from crash/test/test.pd
https://github.com/XRoemer/puredata
I got other crashes with a python programm of mine, which I started via pyext. But I'm not shure if pyext should be used with Purr Data, as I installed it manually.
Best,
Xaver
