Version: 1.9.3 (using KDE KDE 3.5.3) Installed from: Unlisted Binary Package kmail process details bar shouldn't have a scrollbar. I will attach a screenshot.
Created attachment 17153 [details] the unnecessary scrollbar is on the right I think the bar should be high enough for the content, instead of adding a scrollbar.
I do not remember the scrollbar in kmail from 3.5.9 and never seen it in kde4.
