Stack is Dirty?

Yes and no. The titlebar is no different than the edge of the card window. The only thing you get is "mouseEnter" and "mouseLeave" when you move the cursor across those borders.


But since you know the mouseLoc, you can exploit that to determine if you are moving across the top edge.

Is there any message sent in LC when the cursor moves into the titlebar of a
stack? It occurs to me that this would be a good trigger for checking the
modifiedMark to indicate the need for saving. The workaround would be a
frontscript mouseleave handler that checks to see if the final mouseloc is x,0,
but if there is a dedicated message that would be simpler.

Mac-only stack property, the modifiedMark, which can be used to indicate to the
user that a stack has unsaved changes (it colors the window's close button dark
red), but I know of no engine-level way to monitor for changes in the engine.
