when I move outlook 2007 main window or email window from main monitor to 2nd monitor, it briefly flashes on that monitor and dissapears.
afterwards, I can't move it back. if I close outlook and open, the window is shown on the 2nd monitor. it moves back to main monitor fine. but trying to move to 2nd monitor causes this problem again.

this is a problem only if the window is maximized (so DisplayFusion tries to maximize it on the new monitor).

so far I've only seen this problem in Outlook 2007 and it's child windows. Word 2007 works fine, along with all other programs I've tried.

this looks like a bug. I'd appreciate any help in this matter. thank you.

I have the exact same problem. It also occurs when VLC is in fullscreen mode and you want to switch the VLC full screen window. Which brings me to another point: in an older version when you would double click in VLC for it to go full screen it would go full screen on the monitor where the VLC main window was at that moment. Now (I'm not sure if it is because of a VLC update or Display Fusion update) it will go full screen first to the primary monitor and you need to switch the full screen window to the other monitor, then switch back (because the second monitor is on another resolution) and go to full screen again. Is there a way to fix this?

On a final note I want to thank you for creating a fantastic program, it is exactly what I needed. Working on dual monitors has become so much easier.

gemertp - is there any way you can revert to the previous version you were using and test and see if that solves the problem? In order to fix the problem Jon needs to know definitively if it is DF causing it in the first place....
