I'm using latest version and default classic skin - don't know what you mean by build type. There's a 'cursor glitch' when using J (for search). It does something.. for me, it places the cursor at the lower right corner. On windows, you can hover/click here to make all windows invisible (you only see the outlines).. that's where the cursor goes whenever J is pressed and the mouse pointer doesn't hover the playlist window. That hover is the issue, it seems. Something else than the search window becomes active with a "J press" if the mouse pointer doesn't hover the playlist.
