transparency is a bother when using Firefox or mozilla browsers... but, there is a solution... for me, I got a fresh install of Netscape 7.2 for Linux from Netscape's own site ( www.netscape.com ), and it comes with a version of Flash that supports transparency, I use SBC Yahoo and their Today module uses flash with transparent movies... Netscape WORKS... yes, stop looking at me like that, but it's the only browser on linux that works with those sites...
I hope it works on your distro... I tested it on Debian 3.1 (sarge) and on my current Fedora Core 3...
still, I wish it was on Firefox...
