A few months ago I complained about the impossibility to draw right-slanted graphic lines in the IDE.
It was a bug and reported under Feedback Case #50667, as Jason Parsley answered.
The good news is, in 2018.r1 some work has been done; right-slanted lines now show correctly in the IDE.
The bad news, dragging a handle with the mouse still brings back the old issue…
A few months to go I guess, then we’ll celebrate the 15th anniversary of imperfect graphic objects, ever since RealBasic…
