Sorry if the topic is very confusing.
I have, in one case, a TextArea that I use BackColor to flash to give an indication to the user.
I would also like to have an image (jpg or similar), currently in an ImageWell, also flash.
One thing I thought of is to have a Rectangle behind it to flash, but that would cause other problems.
Another would be to make the ImageWell larger with the extra space changing color, but I think that is too complicated.
What else can I do?
