Bug in nembering files

Hello,

Just found this one.
Let's say I'm trying to Rename->Number Files and the first file is busy (e.g. audio file is been played). Then Then the Rerty/Cancel dialog pops up, and I press Retry. Then the Rename window comes back. Now I can repeat this sequence for several times and Rename windows is keep saying "Sequential numbering from: 0001". When I finally release the file (stop playback) and press Retry again and then press OK in Rename window without changing anything, it will not start from 0001, but skip as many numbers, as many times I've tried to repeat before.
