(BUG) BlockEdit window disappears when dragged to another monitor

[APlourde]

If I drag the BlockEdit window to a different display than the one hosting the main Rhino window, the BlockEdit window disappears.

The window is “open” and “active” (the main Rhino window is greyed out) and if I press Command-W the BlockEdit window will “close”

Entering BlockEdit again will open the window on the primary display.

This isn’t just dragging to external monitor, it’s dragging the Block Edit window to a different monitor. E.g. if the Rhino window is on an external display and the Block Edit window is dragged to the main display it will also disappear.

Note, however, there are several “Mac external display UI issues” - see this bug:
