Sometimes a document I am working on seems to stick itself to the very top menu, which means I lose the "search" bar on the upper right, among other things. The only way I can close the document is to go to File/Close because I've also lost the colored buttons on the upper left. It's frustrating if I want to search for something in the doc because the only way I can do it is close the doc and re-open it to get it disconnected from the menu bar. Is there a way I can disconnect it while the doc is open? Thanks...
