Add Enclosure doesn´t work with HP BladeSystem MP for Ops Mgr 2007

Running the HP BladeSystem Management Pack for Operations Manager 2007 and trying to “add enclosure” with the HP Blade Monitoring tool fails with Swedish regional settings. I have tested and switched to US Regional settings and restarted the Blade Service and then the add enclosure discovery worked. We are running English Windows 2003 but with Swedish regional settings. It is not only Microsoft that has problems with other regional settings than the "US". I can´t confirm that other western European regional settings have the same problem but probably. I have a support case open with HP on this.
