I do not have any problems with mouse response, but xmms sure does
skip a whole lot more on my 2.6.0-test1 running on a PIII 500 MHz, 192
MB RAM. 

I usually run Opera and the skipping occurs often while switching
between tabs with the mouse (not when it is done with the keyboard).

Also, severe xmms skipping occurs while scrolling through PDF files
(in Acrobat) while the first few seconds of a song are playing. The
song virtually stops while I scroll. After the song plays for a bit,
scrolling through a PDF makes no difference.

Sometimes, xmms pops up in between songs saying that it could not
detect the audio device! This occurs mainly during heavy disk i/o or
cpu usage.

Apparently it is not just you :)
