I reported this upstream over at KDE. https://bugs.kde.org/show_bug.cgi?id=185672 I first noticed this in my Konqueror's bookmark folder but since then I have noticed this also when using the "move to" or "copy to" context menu when opening up files. What's happening, is that under both circumstances when I open up an item that displays multiple columns and then select a folder to be expanded child folder list is displayed adjacent to the the parent window and not the calling folder. Another example of this in Konqueror. When I try to fill out a form, the autofil "tool tip" is displayed outside of the Parent Konqueror Window.
Forgot to mention qt 4.5 RC1 KDE 4.2
Thank you for reporting this upstream. We will monitor the upstream report for a resolution to this issue.
