Program/Applications open on phantom second monitor

Question

I used to have a second display connected to the iMac. After upgrading to Lion, I disconnected it as it does not really work in the full screen display with Lion. However, some of my programs that were on the second display still think its on that second display. Despite the fact that there is no second screen attached or configured in Displays control panel.
It is annoying because a program will be open, however, I cannot find the program (other than seeing the menu bar on the top). When I click in the Dock, under OPtions, and show program or move to this screen, then I see it (or when I go to Expose), but I can never drag it permanently to see it on the main screen.
Help!

After many days i found solution:
Run the client and get it set up the way you prefer, or Open your saved RDP file
On the Display tab, choose a non-fullscreen resolution.
On the General tab, click "delete these credentials", if possible.
Click Connect .
You will immediately get a local login dialog. Leave it blank and click
OK .
When you are connected and the remote login dialog appears, drag the window to the desired monitor.
On the remote login dialog, click Cancel . The settings dialog should reappear locally.
On the Display tab, you can now choose fullscreen.
You can now save your session with the Save button on the
General tab, as well as save your login credentials.
