I am experiencing a repeatable crash to desktop when dragging to reorder the strokes in the appearance panel.
Create a new document.
Draw a shape.
Add a new stroke.
As one movement, drag the original stroke above the new stroke
Result: Crash to desktop.
As an aside, this killed my installation of Designer!
1st run after the crash produced this…
Splash screen never disappeared. Popup (which should be informing me about a recovery file) white, with only one visible option ("Yes").
Subsequent runs of 1.7.0.293, after the crash, instantly crashes to desktop!
I just tried running 1.6.5 out of curiosity, and that is dead too!
