I am in the wonderful position of having to deal with an INTERMITTENT problem.  Even worse,
the problem seems to occur more frequently on one of my "client" machines - but not so much on my development machine.

Both are 2019 macBook Pro laptops, running the latest Mac OSX and ImageJ 1.52r.

The problem is that *sometimes* (my client reports "roughly every second time") when a dialog box is displayed, it is not possible to edit any of the fields.  Nothing is highlighted, and clicking on the window has no effect (I think).  

The good news is that most of the time, he wants to accept the (remembered in Preferences) previously set values, and merely needs to hit Enter - and all is well.

So...I'm unlikely to spend a LOT of time worrying about this, but I thought I would report it just in case it rings any bells with anyone else.

Has anyone else seen this kind of problem?

Does anyone know what the cause might be?

For context, the relevant plugin displays an image, asks you to select a rectangular region, and then displays a NonBlockingGenericDialog with many parameters (some numbers, some text, one checkbox).  The symptom is that *sometimes* none of the fields are highlighted, and nothing seems to be able to change that.  The dialog can be *accepted* - but not updated.

I'm stumped.
