Interestingly enough, I haven't made any changes to my hotkeys. Could this be the hotkey changes due to a patch. The only relevant information I could see in the spine.log was the following:
Duplicate actions for hotkey Ctrl+R: Next Frame (10), Repeat
Duplicate actions for hotkey Ctrl+F: Previous Frame (10), Zoom To 100%
My guess is changing these keys would get rid of the error but I wonder why it occurred in the first place. Would you still like the .txt and .log?
