Hi The new IE10 does have issues with some websites, it may be due to the coding of the original website which will need to be updated by the web designers.
My Advice is to download Lunarscape Orion which is a 3-1 Web Browser, do a FULL installation and then choose TRIDENT (which is the engine Internet Explorer uses)
I use Lunarscape Browser for websites that do not support Firefox or IE10...
Its a great browser because you can switch which engine to use: Gecko, Webkit or Trident... which are the 3 MAIN engines that all web browsers use.
Its FREE and can be found here at: http://www.lunascape.tv/
