hard disk full warning. yet 90 gigs free....

[Lukasdp]

This warning has been appearing fairly consistently - about once every few days. I'm concerned as its obviously confused given the amount of free space I have. It began shortly after installing the much awaited Utorrent for Mac. & seems to only show up when that is running. has anyone else experienced this message while using Utorrent or could it be something else?
I'm running a MacBook Pro - 2.4GHz Intel w/ 4 gigs RAM and Leopard. The macbook pro is about a year and a half old.
I've included a screen shot to simplify things. Also the warning dialogue disappears after about 20 seconds. And I am using the newest version of UTorrent.

thanks for all the help!

By any chance is the 90gb free on the drive/partition marked 'Audio'.

OS X need space on the same drive/partition that the main OS is installed on.

Alternatively us uTorrent set to reserve space for files you download. If you had say started download on a bunch of huge multi-gb Linux ISOs or something, maybe uTorrent is reserving that space from the system without actually using it.

thanks for the speedy response, no the audio HD you see is a 6 gig express card that I keep my music on, the OS is installed on the Main HD. Utorrent is currently downloading a single song which is a mere 30 MB's. I have never DL anything larger then a gig so I don't thinks its that. I appreciate the response.
