FileMaker Pro 18 advanced

FileMaker 17 client works fine on MacOS upgraded to 14.3 Sonoma. When editing layouts I sometimes have problems getting into boxes for changing the size of an object- e.g. changing the ## of pixels (and some other formatting boxes)- there is no response to clicking in the box- but if I right click and then hit escape I get in. This has been an issue for a while. I don't use containers so can't comment on potential issues with them.

That would be a question to pose to Claris/FileMaker Help
