I un-installed windowblinds completely and re-installed it
After putting back the Primo skinfolder the result was not as i hoped, after putting back
all files and folders from the main windowblinds directory that i made a backup of, it worked....
Only problem are the font settings, they changed back to normal system fonts.
Restarting and clearing cache didn't help.
Basj, thanx for your reply, it works for me this way !
