Toggle: no such object | Button : No such object
sound like a classic... did you check if you have a patch named toggle in your search path?
there's no such patch in the search path. no toggle.maxpat or button.maxpat :) I don't know what causes the issue.
As Jan mentioned, this is almost always a result of a file name conflict in the Max search path. Try searching for toggle or button (without the .maxpat part). If that doesn't work, right-click on the Max app icon and select "Show Package Contents." Navigate to: Contents/Resources/C74/externals/max/ and look for toggle.mxo and button.mxo. Those are the actual objects. Make sure they are there.
Thank you for your replies. The issue seems to be fixed now. There was indeed a buttonS.maxpat somewhere in the search path , very badly named ... Now I know :) Thanks again ! :)
