Anyone else got two-monitor issues with LC9 on Mac?

Sorry this is a bit long, but it needs an accurate description IMHO.

I’ve already submitted a bug report on some strangeness with using the IDE with LC9.0.0 (dp11) on a two-screen system, with the suspicion that it was me doing something wrong - it was just very muddling. However, today I seem to have found something a bit more generic and I’d like to know if anyone else has seen it, before I start the tedious business of simplifying the issue for a bug report.

This is what I’m seeing, on a MacBook Pro running High Sierra 10.3.2. Attached to the machine is a monitor, in the logical top left position, so the mouse can travel from the Mac screen to the monitor by moving North West, as it were. The MacPro screen is 2560 x 1600 Retina (which AFAIKS means it’s acting like 1280 x 800 for normal display purposes), and the monitor is 1920 x 1080. The system is configured so that the initial Mac menu bar is on the MacPro screen (since we don’t always use the monitor).

If I open LC9, the initial screen comes up on the MacPro, as expected. I open a stack I’m working on and drag the initial display (just the first card of the first stack) to the monitor. Going back to the menu bar on the MacPro display, I open the Project Browser to see the stack details. If I click on the little plus (“+”) sign next to the stack name, the browser display unfolds to show the cards in the stack, exactly as expected. BUT if I move the Project Browser window to the monitor, the plus sign has no effect! I can still close the project browser window but I can’t activate it, whether or not I make sure that LC has the focus by clicking on my card display. If I close the Project Browser, switch to the monitor and activate LiveCode from there (for example by clicking on the mirrored menu for LC which appears at the top of the screen) and then open the Project Browser again so that it initially opens in the monitor, it works OK! If I drag the PB window back to the MacPro display, it goes on working.

This is the essence of the issue - there may be other variants with the Tool palette etc but I’m trying to keep it simple.

Does anyone else see this or know of any report? Can’t find anything in the Quality database.
