When opening Thunderbird, I loose my Mac menubar at the top. My dock also disappears. How do I restore these items? They are needed to open, close, cut, copy, etc.

Attached are 3 screen shots. 1 shows the top of the Thunderbird without the Mac menubar 1 shows the left side of Thunderbird without the Mac menubar and the dock at the bottom. 1 shows the left side of screen (Thunderbird is in background) The Menubar and Dock appear.

How do I make changes so that the menubar and dock will always be around when using Thunderbird. the menubar and dock do not disappear when using other apps.

thanks, Jennifer
