My winamp remote project is coming along alright, but this little issue has been bugging me since day one. In IE there appears to be some kind of delay between the time you initiate an onclick event on an object, and when you can do it again. For an example, go here in IE:
http://home.avclan.net/winamp/test.php
click rapidly on the PL button to show/hide the playlist, or double click on a song. There seems to be a half-second delay that isn't there in Firefox or Opera.
I had originally used a 1 second double-click timer for the playlist items so that if you happened to click on a highlighted item after a period of time, it wouldn't just start playing. Because of this issue in IE, I had to disable it because it became almost impossible to double-click and start a song.
