Selena build 6733 (had the same with 6708), WinXP SP2.
Let's say I have a project's folder I would like to rename - I select it in the "1: Project" panel, press Shift+F6 and press "Refactor". IDEA certainly does something with my disk but folder's name is still the same in the "Project" panel. I check the disk - the folder is renamed.
Synchronize (CtrlAltY) - nothing, still doesn't change. I close the Project (Alt+F,J) and then open it again - aha ! only now I see the new folder under it's new name.
Should I file a JIRA ?
