I had this problem, too, when I had an application that had a player on its first card that would be started by an mouseEnter.

I was wondering for hours what could cause my app to "hang" for a couple of secs :-(

Now i just start a player on openCard of the first card of my apps. (Windows only ;-)

I just put an empty sound into that player; open your favourite sound editing app, create a new sound and just add 1 or 2 millisecs of silence !!!

Save it as "" or whatever and start it when your app starts.

Worked fine for me.
