7.0.2.)  I did that, then both worked.  Previously the NotepadQQ 
maintainer said recompile/upgrade libwebp, then NotepadQQ... same thing 
happened. Well, the problem appears to be poor source code in both 
NotepadQQ and KVIRC (most likely) and/or SlackBuilds done wrong... or 
maybe the libwebp maintainer should become aware that some programs try
