This started after I started getting a explorer.exe getting stack overflow error once or more a day. After seeing a similar post here I updated to the newest beta and almost immediately started getting the new error. In both cases the taskbar on my second monitor disappears after clearing the alert, but it would always reload with the previous error. Now I have to restart DF in order to get the taskbar back. Took screenshots of the error and task manager for reference.
Are you currently running DisplayFusion 10.1.2? If so, could you try updating to the latest DisplayFusion 11 beta and let me know if you still get that error?
On the Settings > Options tab, enable the "Check for new Beta (newer, unstable) versions" option
Ok, thanks for confirming you're already on the beta. Could you do the following for me?
Open the Windows Task Manager
On the Details tab, right-click the column header and choose "Select columns"
Enable these columns: Handles, Threads, User Objects, GDI Objects
The next time this happens, send me a screenshot of those stats, along with the CPU and memory usage stats for DisplayFusion.exe and also for explorer.exe
