I created a new chart in v18, with a different watchlist, and the top three lines above the stock symbol line(stock symbol, M, 3M, 15M, h, D, W, M) aren't there.  Those lines include the Files, Tools, Help, Paper:Practice (what's this??), and New, Charts, Watchlists, Easyscans, etc..., and the third line which is the Buy, Sell line.

Since these lines are present on most of my charts, but not on one of them, there must be a way to turn them off and on.  Could you show me how to accomplish this...there are times when I want maximum screen space so I could turn them off, but sometimes I need them and would want to turn them back on for a short while.

Can this be done?

No, those are only in the main window. If you float a chart outside of the main window the File menu and the toolbar will not show up.
