color of selected row of unfocused treeview

[thg2 karate-muellheim de]

Hi,

if a tree view with a selected row looses focus, selection changes color 
from blue to gray, but the sort-column stays blue (see attachment). This 
makes it very hard to read. Is it possible to adjust this color? I'm 
using the default theme of the gladewin32-setup/win.

Regards,
  Thomas
