I use multiple browsers(that way I can use IE as little as possible), one of them is Opera and although it works fine with the forum it will not load the website. It always stops loading after a while, whereas Firefox (and IE) will always load the site completly.
And it justgets stuck at that point, you can see the loading bar the the bottom, I can let it run for a long time and it will just stay the same. (its already weird enough that it takes opera at least 6 seconds whereas even IE can open it in 1.)
I think daft said something about making the site compatible for IE first then tweaking it for firefox users- the reason Opera isn't fully compatible is that no people has cared to mention it before so he can fix it
