That is my guess too Alex. However in the docs it is stated: Important: On Linux, mouse events do not pass through fully transparent pixels. You should avoid creating windows with large, fully transparent areas since you may invisibly block the user’s access to other windows or items on their desktop. On Mac OS X and Windows, mouse events do pass through fully transparent pixels.

OS issue? Can I somehow log this or detect? All I'm getting now is an activated event without a reason. If I could somehow "deactivate" my application when it is activated and the mouse is not where I want it to be that could be a workaround but I can't find how to deactivate an AIR application either. -- View this message in context: http://apache-flex-users.2333346.n4.nabble.com/Activate-events-on-application-tp6234p6245.html Sent from the Apache Flex Users mailing list archive at Nabble.com.
