The repeat on the delete is not working in the code editor. If I hold the delete key down for an extended period to activate the repeat it deletes one character then stops. I tested in 2014r1 and it works as it should.
I see this all the time on more complex projects. For some reason, showing, then hiding the Find/Error at the bottom seems to help it at least for me. Seems to unclog whatever the problem, but it tends to come right back. There is (was?) a Feedback item in the beta period from last year, with several entries. Apparently the Xojo Test staff was able to see it but couldn’t duplicate it. If I can ever reliably duplicate it, I’ll file a bug report.
