On further review, this makes sense to me. Holding down the Control key is an explicit signal to the system that you wish to interact with the application as if it were frontmost. -acceptsFirstMouse: is useful as a guard against misclicks, not against intentional use of the Command key. That said, you probably don't want to lose data because the user misclicked while trying to Command-click in a table view. So I understand why you want to disable this control, and why -acceptsFirstMouse: is insufficient. > >> Note that the behavior can vary on a case by case basis.

I think this might just be how they draw. They listen for key/main/frontmost notifications and change color accordingly. > > I just thought of a work around.

Otherwise panels that become key (like the Special Characters palette) will make it impossible to interact with your control. --Kyle Sluder_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
