that's not weird at all. That's called Internet! OmniWeb, like most versions of Netscape and older versions of IE, does not support transparent stuff like layers, flash movies etc. so it draws the white background. I bet that you will experience the same problem with certain versions of Netscape. Now who is to blame? OmniGroup? No. Netscape? No. Microsoft? Yes. Why? Because like EVERYBODY they are creating browser specific functions which do not work on other browsers. Netscape does this also. There are things which work under Netscape but refuse to work under IE. IMHO, it's the biggest problem on the Net these days, both companies refuse to "meet in the middle". Microsoft just decided to drop Java in Windows XP because Sun doesn't support them like they want to. So, for the standard Windows XP user who doesn't know or doesn't want to install a Java Runtime, no more Java applets! I'm not kidding. I think IE is a good browser and OmniWeb is a good browser. Both have advantages over the other. But both suffer under the inconsistency in the object model the two big companies use since IE uses the Microsoft model and OmniWeb, like Opera, orients itself on the object model the W3 consortium adviced.
It's the old story....
