I started to experience install issues with other apps as well, so after trying several things to fix it, I finally gave in and upgraded to Sonoma. And that fixed it. Apologies for the false alarm!

Spoke a little too soon... I'm finding that I can still select hidden buttons.

That seems to have fixed it, thank you! It does not remember hidden module lables, but that's not a big deal. On a related note, I find when I select a group of buttons for a new tab and then right click outside of the group (on the background) to get the 'Create Tab' option, this results in either a successfully created tab with the selected buttons, a tab with only one button, or a message saying no buttons were selected.

Thanks, Dustin, that did fix my problem! I find I have to drag-select buttons to get the resize and align to work. Just clicking a button and hitting resize doesn't do anything. Easy enough to work around.

Thank you! I haven't been using the selector and completely missed it.

Haha! Then I've been doing it wrong for a long time! Thank you for changing it so quickly.
