That did it! It must have gotten switched off somehow but everything is working great now! Thanks so much!

Settings > Components > Full-screen. Is the option "Use interactive Full-screen preview and Window catalog" enabled?

Thanks for working with me on this!

It is enabled under the settings. I am really at a loss as to what could be happening and why they no longer work together. It makes it more time consuming to move windows from one screen to another.

Go to "Settings > Plugins and Extras". Is the Dexcontrol plugin running? Can you start it?

I just checked and Windows Aero is enabled. I am unable to drag windows from one desktop to another, however.

Can you still move windows around using the mouse in the full-screen preview or the window catalog view? If not, is the Windows Aero theme enabled?

The easiest way to move a window from one desktop to another for me was to use the full screen preview and then to pull up the Windows catalog. I often switch numerous windows at a time to rearrange my desktop so this has proven to be the most effective. I have shortcuts for both actions, but about a month ago they have stopped working together.

Before, I could use my shortcut for the full screen preview and all four desktops would appear. I would then use the catalog shortcut and all four desktops would stay visible and each window within each desktop would appear so I could essentially see every window on every desktop simultaneously. Now, when I use the catalog shortcut, it gets out of the full screen preview and only shows the windows open for my active desktop instead of the windows for all of the desktops. I have not changed any shortcuts on Dexpot since I have installed it about a year ago so I am at a loss as to why they stopped working together. Any ideas?
