Recently upgraded to the latest XDA the XDA Exec and still the built in browser did not work with red hot pawn or many other sites.
So I had a hunt around and found the latest Opera browser, after a much trouble getting it downloaded, microsoft REALLY did not want me to use something else! i managed to get in installed.
It is significantly better then the browser built into Microsoft Pocket Windows PC and renders the pages in full so the fit in the screen (with slight adjustment of the zoom) and all the functions appear to work well.
Just thought everyone who has been trying this would like to know.
In short use Opera available here...

There are versions for loads of different mobile devices.
Only downside is that the Beta broswer i have appears to expire on the 1st June no doubt i will be able to get another version
