...to close the partitioning dialog, even if changes were made in the fstab for a partition. E.g. after enabling quota support for a partition, a nearly unreadable  message pops up (white text on a light green background, see attachment), asking the user if he really wants to execute these changes. After clicking Apply the pop-up closes, leaving the Expert Partitioner still open (so far everything OK except of the unreadable pop-up message). 

If the user now clicks OK to close the partitioner, a new message pops up "No unsaved changes exist". So the user has no other choice than to leave the partitioner with "Cancel". I guess every user would expect that upon "Cancel" his changes have been canceled, but in fact, his changes have been saved - when checking again, the quota support is enabled.

IMO, this is very confusing and doesn't make sense at all from a usability point of view - even if the changes to the fstab are already saved when closing the pop-up, users should be able to leave the partitioner with OK (and not get a message that there have been no changes when, in fact, there have been changes, even if it was only to the fstab and not to the partitioner itself).
