When I use the Flash CS4 brush tool in "Paint Inside" mode it erases part of the strokes around shapes. For rectangles it erases the stroke on the top and left hand side where the brush head crosses it, though it never seems to affect the other sides. The effect is less consistant with ovals, but it breaks the strokes at some points. I am using Flash CS4 version 10.0.2 on Windows XP, and I have checked for program updates through the Help menu. Here are two examples:
If I understand right, the brush tool shouldn't be changing the stroke anywhere in this mode. I would be grateful for any help.
This has existed for a very long time in Flash, at least back to version 8. I'm not too sure, but it certainly only affects two out of the four sides of a square. There is a bug on this, so I will send it back for review.
