[WIN VISTA] Installing on external HDD

Hi,

I installed "xbmc-9.11-a2.exe" on my external hard drive (H and choosed the option "portable mode" during install.

Problem is that, when i disconnet the hdd and connect it to my laptop (also win vista, drive letter is also H all settings / library are gone.

somehow everything is stored under "C:\Users\pwaveW\AppData\Roaming\XBMC" ...

any ideas how i can get it to work, that all data is stored on the hard drive?

so everytime i plug in the external hard drive into another pc it creates automaticly a "XBMC" folder under "C:\Users\pwaveW\AppData\Roaming" .. how can I change this permanently so that it uses the data and profiles from

[ExternalDrive - letter H]:\XBMC\

is this possible??
