I keep on getting the same crash happening,

Say i am in the middle of setting up an animation - i want to know how a frame is going to look, so i click the photoview preview window icon. which works fine and i can view the preview, if i then do not close the preview - after making a few adjustments to my motion study. sometimes it happens on the first one.

Quite often i forget to close the preview - solidwokrs does not totally crash i can still select things, and i can open the drop down menis, but most of the options are grey.

but you cannot do anything in the motion study plane.

normally end up having to get out using Task manager, Ending solidworks, and for some reason the Auto Recover also never ever saves the current assembly. just some random sub assemblies.

any ideas why?
