I'm assuming you are talking about the View / Record menu item.
I'm curious... does that mean the red button in the KM Editor (and the pop-up window) turns off (disappears), or does that mean that it stays on while just not registering any activity? Either of these could result in the description of "stops recording after just one step."
If the former, my first plan would be to see if any other macros, including hotkeys and periodic triggers, are somehow doing something to turn off the recording. In order to test that, I would disable all groups manually and try recording. If the problem still exists, then it isn't interference from any macro.
SOLVED: Wow, I can't believe it's fixed. As you said...this was something I thought as well, however I originally just did a scan of everything to see if there were any trigger hotkeys with an "R" and didn't see any. But after this mention, I went ahead and actually disabled all macros. Then...like magic, it works...
Here's the interesting part - I started enabling chunks at a time and testing again, assuming I would discover the culprit. Now that everything is enabled as it originally was, the record function still works great.
If I had to guess, maybe there's a macro that runs indefinitely and disabling it actually aborted that disruptive macro. If the problem persists in the future, I'll try to disable in smaller increments to see what did it.
You are welcome. I was only 20% sure that my idea would solve your problem, and then, when it failed, I'd be politely blamed for wasting a lot of time. But if something only takes a minute to test, it's worth testing, even for only 20% chance of solving the problem.
It doesn't really matter what the correct diagnosis is, if you are happy. My guess is that you didn't re-enable the troublesome macro or macro group. But again, there's only a 20% chance that I'm right about this.
