TotalSpaces + El Capitan + Mission Control + Hot Corners = issue

Wow, thank you for the very detailed issue report. This appears to be related to this report. I haven’t yet been able to reproduce this issue myself, so there might be a common setting between your system and the other customer’s.

I’m curious, are you in a position to install and try version 2.3.6 of TotalSpaces to see if the issue also exists? I will ask the other customer as well.
