From time to time, for no apparent reason that I can see, the menus and toolbar at the to of the Carrara UI will disappear. You can see the Tray Tabs at the sides and bottom of the screen. These can still be pulled out. [There's no Assembly Room workspace shown here because it's on a second monitor.]

When this happens, I can only do a CTRL_ALT_DELETE to get out of Carrara. However, the Task Manager always says that Carrara is still running, and a Carrara "Do You Want To Save?" window shows up in the background. I can always slide this out from under the Task Manager window, and say "Yes" so I don't lose any work. Then, the Task Manager says Carrara is NOT working and we close and re-open.

Anyone else seen this?

Unless you have a crankin' computer, I probably wouldn't have Carrara and Poser running at the same time.
