I am fairly new to Mathematica and have just installed Mathematica 10 on a Windows 8.1 system. The Algebraic Manipulation Palette does not seem to function correctly. In particular, clicking on a command from the palette, Expand[ ], for example, causes the command to be highlighted in the input area for a brief time and then to disappear leaving only a single box for the entry of an expression. The actual algebraic command, Expand in this case, does not appear at all. Has anyone else experienced this behavior or am I misunderstanding the use of the palette in some manner? Thanks for any comments or help.
Thank you for the guidance. That works as you explain. Sometimes the simplest things elude me. Thanks again.
Try this: First select the expression in the notebook using the mouse, so it is highlighted. Then move the mouse and the click on the Expand[*] button in the palette. While moving the mouse to click on the Expand[*] command, the expression will remain highlighted.
You have to select the expression first, in the notebook, before clicking on the command. The command acts on the currently selected expression.
