Some sites are developed to work only on IE. I think this is because either poor development skills (I mean the site developer only tests his site on IE) or because of some deal with Microsoft – conspiracy theory 
Anyway, on Ubuntu, without IE, this is really annoying.
I found the sol. lately. But before you go for it, send to website master and tell him that this is silly.
The sol. is using this nice software: IEs 4 Linux
And here is a nice explanation if needed IEs4Linux – Internet Explorer 5.0, 5.5, 6 & 7 on Ubuntu Linux

Trying to Install IEs4Linux I faced some problems:
1- The ones mentioned in th second site and following his steps, it was solved.
2- Installation stopped at some point telling that a file can’t be found (the file is MFC42.cab)
and – thanks to bloggers – I found the solution again
download the file manually from http://activex.microsoft.com/controls/vc/mfc42.cab then paste it in its supposed folder and try installation again
And at last, I have ie6 and ie7 installed on my dear ubuntu.

After using – or trying to use – IE on ubuntu
ie7 doesn’t work. It opens normally but does not open any page – actually it’s a beta feature in IEs4Linux
ie6 works but it crashes a lot

My final note: as ie through IEs4Linux crashed more than it worked, I’ve decided to try another explorer.
I’ve chose Opera and – a good choice – it worked and opened IE only site
