Steps to reproduce: 1. Create a new partition with size 5000 2. Change your mind, and edit it to raise the size from 5000 to 7000 3. Once you click OK in the partition editing dialogue, the size is still shown as 5000
There's been a good bit of work done on the partition editing dialogs since the beta. Please give rawhide a try and let us know if it works better for you.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
