After checking the obvious things like; having the correct machine selected, making sure I was not in Design ( as mentioned above), there was still no response from the toolpath manager window. I called CNCsoftware tech support and they fixed me up in about 3 minutes. I had to go find the my mcam 2018 folder and rename it. This resets the defaults. It worked fine after that. The down side was I had to re-customize my screen setup.

I have a file that the tool path manager seems to be stuck. When i click on any part of that window I get a warning ding from the computer. I've tried re-opening, rebooting and re-opening, with the same result. I had just exported my toolpaths to a similar part file just before this started happening. Would anyone have any idea whats going on here? I just opened another file and it is doing the same thing.
