Re: OT: icon problem

Hi Peter,

Just a quick if late follow-up.  I finally sat down with this today,  
and think I've got it figured out.  You got the right area  
/usrr/share/icons.  In my case .../KDE_Classic/cursors/col-resize  
points to split_v and row-resize points to split_h.  That does seem  
backwards, probably a typo somewere during setting up the theme.  That  
mis-pointing is tre also of all the Oxygen_color themes I have.  The  
only ones not to have that problem are breeze_cursors and Breeze_Snow  
where the resize files are real, not symlinks, and the split_h points  
to col-resize, which is correct.  Now I've just got to figure out how  
to file this as a bug with Gentoo, and wonder if it is their packaging  
or actually from upstream.

At least I've tracked it down.  Thanks for the help.

Jack
