I have displayfusion pro (7.0), purchased on steam, running on a two-monitor setup.
Occasionally DF seems to freeze, noticable by flashing icons on second monitor taskbar freezing. When one tries to click on them, windows reports DF has stopped responding. This seems to occur rather randomly, but there's probably some pattern I've not noticed underneath.

Thus I ask, how can I diagnose and troubleshoot the issue? What information should I look at and are there any known causes that could be relevant?

Thanks
