I tried searching for other examples of this behavior in the forums and only came across the following:
Included is a smaller subpatch from a larger project. I am changing the outline color of a button, which is working fine using the button's attrui set to 'outlinecolor'. However, when that button receives a bang from another button while also receiving attrui changes, the color changing button's blink state stays in the on/blink/yellow state. Is this normal behavior? Am I using attrui incorrectly? I have observed it on both Mac and Windows machines.
