Obviously you have NO CLUE what I'm asking. My question has nothing to do with the lock you're referring to. It seems more technical than you're thinking.Is the source locked?

The don't be stupid prompted my response. I wouldn't come here for such a simple task.Considering the option being shown and asked about is one of the very few things in OBS that can prevent a source from being resized, it's a very valid question. Try not to snap at and insult people that are trying to help you. Your explanation on what the issue actually is, and details thereof (i.e. logs, screenshots, etc.) make it difficult to provide anything further.
The other option is locking the preview itself, which can be checked in the Edit menu.

Thank you so much for posting this response. I just had the same problem while in full screen. Escaped and it's all good! :)It's been seven months with no updates here, so maybe OP got it sorted, but for anyone else fining this thread by search, like I did:
I suddenly encountered the same problem, on a Mac. Everything was working fine, I added a new scene and source during a livestream, and suddenly lost all ability to resize that or any other source. The bounding box is there, the grab handles are extra large, but if I try to click on anything in the Preview window, and the selection is simply cleared with no effect on any sources. The Transform settings have no effect. Neither Preview nor Sources are locked.
But there was a simple fix - resize the OBS window itself (just a tiny bit), which causes the Preview window to reset its zoom, and everything returns to working normally.
