You should probably move this to the SolidWorks Add-ins/Photoview 360 forum. You are much more likely to get an answer there. Move should be available to you under the Actions to the right of the page.
don't think I am following here
version and service pack?
could you also outline the steps in 1,2,3 format?
does this happen on even the simplest of assemblies or only one this one? if you can, post an example that shows the same problem
I sometimes get that camera jump after I do a rendering (not animation). I haven't figured out what factors make it happen. I thrash around to get the camera view back, and I can't define that process any better. I know this isn't much help, but at least you can see my set up. Maybe we have hardware or software in common.
