Canvas Draw has many nice features not found in other draw programs. I just got the new version as Version 6 would not run under Monterey (I had a perpetual license that I had to fight tooth and nail for)
This version has some really nasty characteristics.
placing a TIFF, or dragging the file into the document, does not place the whole image, I went back and tested on version 4, same problem. JPEGs work correctly.
Resizing the window, changes the size of the document shown (it should not) but the magnification indicator (lower left) does not change. So if you change just the width, you get a not proportional image! Version 4 didn’t do this. See two screen shots.
These seem like pretty nasty bugs.
