On a MacBook pro OS 10.4.9, with a USB Flash drive partitioned in 2 partitions (just to analyze the facts), one named "Mac" formatted with Apple HFS journalized, the second named "PC" formatted MS DOS (FAT16):
I observed and confirm all the points above by Bastiann Harmsen on the "PC" partition, but no problem on the "Mac" partition.
Reboot seems to fix the problem.
OK , even unmounting and remounting the drive seems to fix it.
More observations:
1) the name is changing only on new folders created after the last mounting.
2) the behaviour is not the same if the presentation is with icons or with lists. In the latter case, clicking after the list restores the original names, while not in the former.
3) it seems to be a problem with the graphical interface and some kind of cache update: it is always the latest name given to a folder which is given to the earlier created folder when you click on its name.
4) the problem is not fixed by an upgrade to OS 10.4.10
PS: before making myself the tests , I did'nt believe what my friend, owning this MacBook Pro, described.
Any other comments are welcome!
