Vista - weird problem with remote control on vista x64 MCE

Hi,

I've googled arround for hours but could not come with a solution so hoping someone here can help me out.

My remote control (X10) fails to work in MCE for online media pages and online TV pages. (that are the html pages in Mediacenter like the dutch 'Uitzending gemist' or some html based games) . I cannot use my arrow keys anymore to select programs or use the OK button. Some buttons on the remote still work , like volume up and down. If I control it with my keyboard or mouse it works just fine. This only appears in vista x64, not in 32 bit vista. It probably has something to do with the 64 / 32 bit IE (I've default the 32 bit IE browser since 64 bit does not have any adobe flash available), but at the other hand, I believe its a different browser object loaded in MCE for showing those special pages. Anyone knows a solution for this weird problem?

Many thanks!

Leo
