See the Report an Issue section of this forum (Tab at top of screen). This is the section of the forum intended for reporting possible bugs. The Report an Issue section will pop up a form to fill out that will ask you for just a bit more info than you have posted here. Hopefully, FileMaker Tech person will then reply to your post either with a request for more information or to confirm that this bug exists. (They are really short handed right now so any "official" response will be a while coming.)
Oh, thanks. I couldn't find that before.
