Issue confirmed.
It seems it does save the menu order the first time. When you reorder the second time it doesn't save that (with the message on top that changes have been saved). reloading doesn't work eather, you have to move away from the menu manager and come back to be able to do an edit again.
Tested system: Win7, Chrome
