Please help,

I have an iMAc, runnung OS 9.1 w/ a DSL connection. I have been a happy and grateful user of LW for almost 2 years. I recently upgraded to the latest version and things have never been so bad. The movement of the cursor is so slow and the movement on screen is miserable. I can't scroll the results, typing in the search is painful and trying to download music is torture. (once the download is in progress, things are fast and fine) The other applications running are affected somewhat, but not to the extent the LW screen. I tried to download LW again, I was successful in my subsequent attempts, but the problem continues. Is there any way to down grade back to the old version?? Please say YES.

Thanks, Holly
