Rarely, if ever, did I have an issue with Poser crashing, all versions from Poser 4 to Poser 11. Then SR5 came along. Every other click on the parameter dials, saving or using the graph caused a freeze or crash. Ended up deleting and reinstalling Poser 11, then updating to SR4. Seems to be stable again so far.

Dump SR5.
