KMix keeps popping up!

My SUSE hard drive "died", so I have had to install it again on the new drive. I have installed all the upgrades, including KDE 3.5.4 "release 62.1" Now, when I boot, the KMix mixer window is always on the desktop and I have to exit KMix each time. Then, next boot, it's back again. It's not a big nuisance, but I wonder if there is a way of stopping it happening. I have tried having the 'dock into panel' selected and not selected. No difference. Has anyone else had this problem and managed to overcome it, please? Many thanks for any advice. Keith
