It seems that way, I can use the Debug button and the script will run and complete but if I add a breakpoint, it runs and stops as expected but then it locks up (sort of), most likely as I can’t see the STEP button and can’t press it to continue. So I think it is working but hidden somewhere!
The Monkey editor sometimes gives me issues when on multiple monitors, e.g. if Rhino is on the Monitor 1 and Monkey on Monitor 2, when you use the laptop the next time with a second monitor Monkey can’t be seen! I try to do it the other way, Rhino on 2 and Monkey on 1 as Rhino will find its way to the laptop when only one monitor.
I’ve found the registry settings for the Monkey window and can get it back if needed, here’s a screenshot, edit the MainWindowPos_left and you can get Monkey back.
There must be registry settings for the Debug window but I haven’t been able to track them down.
This seems to be best place to start as Debug is a separate window.
