Explorer, possibly styler/windowblinds

Hey guys, this is most probably a stupidly obvious thing (evidently not, for me), but in my attached imagie I have a strange line appearing in windows explorer. I'm using windowblinds, styler, and findexer in my explorer setup. It's been bugging me for a while, and I've searched on how to get rid of it for ages. Any ideas?

Please excuse the amazing ms paint talent.
