kmix issue with mwheelevent in TDE

hi tde fans! I notice there's the systemtray kmix applet which works quite well in TDE for managing sound volume but there's a little benign issue here with r14 on debian jessie. When I use the mousewheel over the kmix volume speaker in the system tray, the volume changes but when the kmix icon is clicked on to expand showing the vol indicator, the position of the vol indicator remains unaffected. not a top priority of course so I'm patient to see a fix on this.. thanks
