@Nick_Dale, I've moved your question to a new thread as it's not the same as the thread you posted in. Please clarify my questions below.
Can you reproduce this issue in Safe-Mode? Help > Troubleshooting > Restart in Safe-Mode
What exact version of Komodo? Help > About Komodo, on OSX Komodo > About Komodo.
What OS are you running and what version?
These two statements are contradictory. Please clarify.
"In both apps"? What apps are you talking about? Are you running two Komodo's at once?
Your issues MIGHT be related to this ticket:
I'll hopefully be releasing a "nightly" soon that will include that fix.
