A family of Microsoft word processing software products for creating web, email, and print documents.
The only way I can see to have the Properties and Group buttons grayed out but still have the other buttons in the Controls group enabled is if you don't really have the check box selected, that is, if the cursor is in ordinary text.
Can you show a screen shot that includes both the ribbon as in your previous post and the location of the selection? Also, do you have any kind of editing restriction (protection) applied to the document?
