Difficult to imagine other listbox properties bringing it about, but I believe the short attached example demonstrates a very odd AnyScreen list format bug w/ PROP:BarFrame. This bug has been consistent for me because the offending line of code was deep within a derived WindowClass that I could not initially suspect.
Might anyone be will to test & confirm?
AnyScreenWindow.clw (1.5 KB)
Listboxes have other issues too. I’d just send your example to support so it gets into the system. Maybe they can fix it before the next build.
Appreciated. I did post a PTSS, but usually never see any response.
Hard to imagine that EIP works w/o errors, but will move on to test.
