I just upgraded from Mac OS 10.3.3 to 10.3.4 and from iTunes 4.5 to 4.6

Now when I download songs from Limewire,
they no longer show up in my iTunes Limewire
playlist. They are only in the appropriate shared folder on my hard drive. I have to drag them into Limewire to play them. Not that it's a big problem, but never had this happen before until I did both upgrades. Songs ALWAYS downloaded directly into iTunes.

I checked the Limewire preferences-and the iTunes
support is still checked (Limewire version 4.0.5).
I'm afraid to upgrade to 4.0.7 cause I previously had a terrible time with Limewire disconnecting my Internet cable connection. 4.0.5 is the first version that didn't cause this problem for me, also don't know if the latest version would even fix this.

Any help or suggestions would be greatly appreciated.
