Show overview grid not working in Mojave (10.14) on built-in screen or external monitor


I’ve got the latest (v.2.7.5) of TotalSpaces2… This was working the other day but I installed an OS patch care of the AppStore that required a reboot… I can no longer get the overview grid to work at all whether I use an external monitor or the one built into my MacBook Pro without the external screen. I have not tried the pre-release software 2.7.6. Thoughts??

ps. in playing some more I find that even if I use the menubar to select a different space it refuses to do the switch. I have to select different apps in the dock to force a switch that way… That’s the only way to switch the currently selected space at the moment…
