Hidden ribbon

I’ve noticed when working in Excel 2010 that the “fill color” command does not work if the ribbon is hidden. For example, if I say “home” “fill color”, the letter “h” is entered into the cell. If the ribbon is already showing then the command works no problem. I’m using VoicePower version

If my memory serves me correctly (and it doesn’t always), I think I’ve experienced similar situations with other commands in either Word or Excel when the ribbon is hidden. Has anyone else found something similar?
