What operating system are you using? Did you use any of the window resizing hotkeys in DisplayFusion, or do the windows just open this way?

Thanks,
Jon

I have just released v1.4 of DisplayFusion. Can you please give it a try:

If it still does the same thing, try going into the options and disabling the hotkeys. That will prevent DisplayFusion from resizing any windows.

Thanks!

The new version of DisplayFusion (v1.4.2) should correct this issue. It is available for download here:
