Craig, it is even stranger than that :) If you use the eraser to remove all paint, then as you say, such messages (e.g. mouseWithin) are not fired. If you set the imageData to empty, such messages (e.g. mouseWithin) are not fired. If you set the text of the image control to empty, such messages (

Re: firing mouseEnter msg of an Image control which was painted

Putting a mouseWithin handler within the image shows that this message too is not fired, unless the mouse pointer is over a painted area. Again, once the image is selected, then mouseWithin is sent even when the pointer is over a non-painted area. Bernard On Mon, Feb 2, 2015 at 3:10 PM, Bernard

Re: firing mouseEnter msg of an Image control which was painted

Re: firing mouseEnter msg of an Image control which was painted

A few ideas, none of which may work for your situation: - Fill the image with the same background color as your card, so the image only *appears* to be transparent when not “painted". - Place an opaque graphic (could have its blendLevel set to 100) directly behind the image and do your mouseEnt

Re: firing mouseEnter msg of an Image control which was painted

Bernard. To hell with the Superbowl. This is important. Confirmed. The paint inside an image is the only "object" that triggers messages. The enclosing image becomes "invisible". Worse, if you erase all the paint, the image remains recalcitrant. It has been spoiled. One might say it stinks.
