This is a sporadic issue where sometimes f5 will bring up the brush window above any open documents whether they are floating or docked, and sometimes it will show up below the floating documents. In that case the only way to get to it is to move the documents, which is enormously cumbersome. I tried searching for this, but can't find any mention anywhere. Does anyone know how to deal with it, is there an option somewhere that I keep triggering unknowingly or is it just a glitch? I would really appreciate some help on this one.
