I am applying images as skinning for scroll bar components VScrollBar for List Component . I got good effects on up-arrow, down-arrow, track also, But in Thumb , I applied a JPEG image as a skin. Some times, the pages goes to very lengthy, the thumb
images size was reduced to small & got pixelated. Let me know, How to safe the thumb skin.
I assume this is in spark skinning. You might want to try the fixedThumbSize property.
<s:VScrollBar fixedThumbSize="true" />
