Does Poser 8 or 2010 freeze up when you delete a figure? Maybe it happens when you add or remove an item in the library? Does the Libray come up blank?

If you are running Google Chrome web browser that may be the problem. If it's open to a page with any flash content (like every page has now-days) it will cause Poser to flip out. This also happens if certain Adobe apps are open with Poser. I know Premier and Adobe Bridge cause this problem there may be others.

So here's the low down if you have an Adobe program open it may interact badly with Poser causing Poser to freeze. This includes web browsers that don't sandbox flash. Firefox and IE appear to isolate Flash so it can't cause this problem. If you close the offending Adobe program Poser will begin responding again. The freeze occurs on Poser's native (gray) dialogs. It won't happen on OS native dialogs like the File Chooser when you save.

This only effects P8 and 2010. It's probably because of the flash based libray. If Poser gets stuck deleting a figure or switching rooms check that you don't have any Adobe running in another window or in the tray (Bridge can hide in the system tray) As far as I know this only effects Windows systems.
