Found another bug.
This time, Nokia Map Loader and Maps Updater.
If you have a memory card also in your Nokia N97, Map Loader/Maps Updater (at least for me), seems not to find your Maps folder and does not recognise your phone as a compatible maps device.
Says on the first screen to put your phone into PC Suite mode, the error says Mass storage.
And you then get warnings such as "You have connected at least one phone without a valid maps drive".
Garbage.
Pure garbage.
Bye
