I found a few bugs in leopard 10.5.1

-when i try to lower the amount of sound that the micro receives in the speech control panel, the slide bar moves himself automatically back to the highest level
-when i move the slide bar in the itunes control panel (more specified: the slide bar which controls the amount of seconds that are taken of songs to mix them fluently from the one song to the other) i see the bleu slide thing 20 times (like a lag)
-imovie doesnt work :s

(sorry for my bad english, but i can't express this better)

where can i tell apple about these bugs?

You could use bugreporter.apple.com You need an account to do it.

i have none of those, and i'm running on Leopard 10.5.1, on macbook pro. Weird?? everything working great!

I don't have the first or last problem but the crossfade slider in itunes does have a graphical glitch. The pointer leaves a ghost at every increment until you release the mouse button. Still works fine. This is on a new 24" with all the updates.

i solved the imovie problem (i did an update and now it works very well).
The other two problems remain...
(also 24" alu imac)

i have the problem of the former though. but it seems to lower itself down again.

pairing bluetooth devices doesnt work in 10.5.1
