I needed to make room on my Windows 7 partition to install a new program, so I did some searching on how to resize a partition and it told me to shrink the OSX side and then expand the Windows one into the free space from Windows.

That didn't work, so now I have a 245 GB boot partition (my main OSX one), then roughly 10 GB of free space, then a ~61 GB Windows partition.

I tried to just drag the corner down on the OSX partition and click apply, but all it does is unmount and re-mount Windows 7 without changing anything.

I don't really care whether I expand the Windows partition into the free space as I originally intended or just re-expand the Lion one into that dead space, but there's about 12 GB of space there that's not doing anything, and I'd like to use it.

Any ideas?

AFAIK, you cannot resize the boot partition while booted from it. Instead, boot from a Mac OS X install DVD, then run Disk Utility there to resize your boot volume. – fanaugen Mar 8 '12 at 7:19
Also note that you won't be able to resize the Windows partition "upwards". You can generally only resize partitions at their "end", not at their start. – pmdj Jul 2 '12 at 22:31
