I use subject search several times everyday. But now such searches never find anything and don't open a search results window.
Is something misconfigured or is it broken?
try to rename your plugins folder to say plugins2, restart and see if you can reproduce the problem. If N++ works fine with plugins disabled, try to re-enable plugins folder, and then try to remove plugins one by one until you find the offending one.
