Can Someone Help Please?

I'm in the middle of a project and suddenly I can't zoom in to most of the tracks in the project. I can't find any setting that changed anywhere, although surely I'm missing something. So I'm at a dead stop on this mix. I've used reaper for years and I've been running my same customized commands for a very long time. It occurred on 5.50 and I just upgraded to 5.51 to see if that fixes it and it doesn't. Any help would be greatly appreciated.

Pretty please? =)

I'm assuming you just use the mouse scroll wheel to zoom in and out, and now that does nothing? How were your customized commands set up previously? Another poster had an issue with the timebase settings; he had it set correctly but the behavior wasn't correct. He set it incorrectly and then back to correctly and reported back that it was fixed. That could be something to try.

I have Z X C and V mapped to zoom in and out horizontally and vertically. Now they don't work at all on half the tracks in the project -- while others zoom in and out just fine. I've tried setting the tracks to other views and then back to Default and I've checked through all possible toggle commands in case I accidentally struck another key combo or something, but I can't find anything at all.

Maybe you have locked something? Right click on the lock toolbar icon and see what's locked.... Is there anything different in the nature of the tracks that won't zoom anymore?

There are no locks enabled and there doesn't seem to be anything else different about the tracks. Odd.

In case it helps someone else: It ended up being a particular track that was causing it. There was nothing different about that track, but all other tracks were its children and they wouldnt zoom. I copied the things in that track to another, moved all the children to the new parent, and everything works as normal. Even putting new tracks in the previously faulty track would cause them to not zoom. Just an odd glitch I suppose. Thanks for the replies, guys.

They weren't collapsed, that's the first thing I checked. But it did act as though that was the case. Maybe it got stuck? Not sure, but it doesn't make much sense. But it was as simple as replacing the track.

Glad you got it fixed and thanks for posting back with the answer.
