Hover state - Unwanted Flashing
When I create a standard button (not radio or Check box) I always get an unwanted flashing when I test the hover state. This happens whether I put an icon or text in it or not. If I make it square, or rounded oval it does not matter.
This seems like a significant Bug to me.
The only solution I have found is to create my desired "states" in Photoshop and use "picture" as the fill for each state.
Unfortunately this prohibits the ability to add any of the icon art to a button.
I see several responses to this topic but none seem applicable.
