You need to check the Auto-save button for each workspace that you want to remember your active browsing state. When you come back to that workspace after restarting OmniWeb, you'll get your windows as close to how they were as is possible (often including partially filling out forms). If you want to go back to the "clean" state, just click the restore snapshot button in the workspace window and the windows and tabs you've accumulated since taking the snapshot will be discarded.

Well, that's how it is supposed to work, and works for me. Re-reading your post, I see that you've got it set that way, I misread the first time.
