Dual Monitor Issue

[rjbokleman]

macOS with MacBook Pro, 15" 2018, i9, 32GB RAM, Radeon Pro 560X, 10.14.5 or .6 doesn't matter.

PixInsight is loaded onto the external Thunderbolt Display.  Somehow, must have dragged my (probably related to my second issue below), Process Icon for Curves Transformation to the native MacBook Pro display.  It is now stuck on the native MacBook Pro display and I can't drag it back to the external monitor.  Is there anyway to get it back on the other display??

macOS seems to have an issue with the cursor too.  If I click on PixInsight (running on the external display) after having my mouse on the native MacBook display I get some kind of selection box every single time and it causes me to accidentally move things around at random.  To reproduce this, I click on the my native display (like this post I'm writing now in Safari) and then click anywhere in the center of the PixInsight workspace on the external display to continue my work....I now get that selection box.  It's driving me nuts.  Just so you know, I have tap to left-click, not push to left-click on my trackpad enabled.  Never use to be a problem, but it sure is now.

I managed to get the process icon back to the main screen, but the margin of error/space when dragging it is so minimal its extremely easy to miss.  The issue happened again this morning....the UI gets stuck in some kind of situation whereby every place I move my mouse cursor it's dragging and resizing windows in my workspace and outside it all over the darn screen....making controlling PixInsight nearly impossible.

I use dual screens on an iMac and don't have a problem, sorry I know this doesn't help very much
