I thought that 24bit alpha was available (but slow) in IE7?

Trevor, I have some experience with the png thing :)  There is no
problem overlaying 8 bit png with transparency in any browser.  The  
problem starts in IE when you use PNG24 with alpha transparency.   
PNG24 with normal transparency works.  Its only the alpha transparency
that breaks things.
