E.G., I enter some data in a cell ( it matters not whether alphanumeric, text, currency) and upon completion of that I routinely am unable to enter anything into the next cell without using the mouse to click on the formula toolbar in either the blank area to the right of the equal sign or the checkmark itself. I've gone as far as unstalling and reinstalling from a clean install disc and same occurrence. What prompts Excel to make a cell "active" and ready for data? Obviously I can work around this but if there's a solution...Thanks for your time.
