For you SPB Mobile Shell fans, there's a working fix to re-enable the HTC pop up menus with MS v3.5.3

Its a registry fix, I made a quick cab if anyone is interested.
Code:
[HKEY_LOCAL_MACHINE\System\GWE\Menu]
CUIHandler = 1 (dword)
[HKEY_LOCAL_MACHINE\Software\HTC\HTCMenus]
EnableManilaCheck = 0 (dword)
