It really shouldn’t come as a surprise: When you use new stuff it doesn’t really always work the way you want it to.

We’ve been building our new charts in Flex 2 (beta 1-3) from Macromedia/Adobe, since it had a lot of the features, we’ve been looking for.

The first two betas demanded a new flash player, version 8.5.

That player made the charts show up as intended in Firefox and Opera, but not in IE 6&7 (which instead runs flash player 8.0)

If we uninstalled the flash player and rebooted on a computer, we got this impressive result:
Firefox: still runs 8.5
Opera: doesn’t run flash
IE6: still runs 8.0

To put it frankly, both Firefox and IE behaved quite differently than I would expect.

Installing the player again and rebooting gave us this:
Firefox: still runs 8.5
Opera: runs 8.5
IE6: still runs 8.0

This Monday the new player (9.0) was out, so my hope was that it would finally work in IE. I tried to install it as well as Opera on another computer and got this result:
Opera runs 7 (? - must be included in Opera these days)
IE: still runs 8.0
Firefox: runs flash player 9 - but doesn’t show flex components.

I’ve been on the phone with Macromedia/Adobe Denmark, Europe and US and the only thing I can tell you for sure is: I don’t know when it will be fixed.
