The top two bitmap cursors almost completely dissapear. They are a VERY light gray or transparent. The tool is not usable.
I tried adjusting the image color I was edting (Black, White, etc) to see if this would help, but no luck. The color of the background had no impact on the ability to see the cursor.
I tried both my laptop and extermal monitor.
I attempted to do a screen shot, but it was not visable:
I am using the latest cs6 version.
I checked this o an image with black areas and white. Over the white the tool is black and the lasso lines are blue. Granted the icon is very thin lines but quite visible. Over black the icon is also blue. I am on a Mac as well and latest CC Fireworks
