windows switch between workspaces

[Mike]

The bug-filing system really discourages filing bugs, but it seemed like the right thing to do so I persisted. This issue is already being discussed in askubuntu.com but the format there doesn't seem to be addressing it as a bug. This is the thread:
http://askubuntu.com/questions/198277/no-auto-move-of-applications-between-workspaces

My input is that I'm experiencing something similar: Dual screens positioned side-by-side with mirrored mode disabled. I usually have Remmina open in full-screen mode on the right monitor and Chromium or something open on the left. Today when I click my mouse in Remmina the entire Remmina screen disappears. At first I thought the app was crashing but found that it had moved to my second desktop which I don't typically use. I can work with it there, but then suddenly it moved back to the first.
This has happened several times and only started happening today so perhaps it's a regression with a recent Unity update?
