Hi,

I have this page that I am working on about 3 column layouts with rounded
corners, alpha etc.

http://www.nrkn.com/3ColRoundAlpha/

It's unfinished, but while testing I've noticed something strange. I have
taken some screenshots to illustrate this:

http://www.nrkn.com/3ColRoundAlpha/problem/

The page looks like I expect it to under IE, Opera and Firefox (6/7,
8.54/9b, 1.5) *locally*.

Just in Firefox though, something weird happens. If I minimise and then
restore Firefox while on the local copy of the page, all the parts of the
page that have a png with alpha transparency become darker except for the
png which is the background for the right-hand side of boxes, which looks
normal.

Now, if I upload the exact directory structure to my website and view it
with *any* browser, the right-hand background mentioned above is missing
entirely.

Is it just me or does it look like that to everyone else too?

Big WTF!

First, what's this weird thing that FF is doing? Something to do with the
gamma in the png or something? Weird.

Second, what's different about the right-hand background? It doesn't
trigger the gamma-bug thing mentioned above in FF and you can't see the
background at all in any browser.
