Tab Key in Email
I have always been able to use the tab key to indent in an email. Just a few weeks ago, this ability disappeared without warning. Now, pressing the tab key erases everything I've typed and returns the cursor to the upper left corner. Dumb idea!! If you needed to disable the tab key, why not just make it so the key no longer responds instead of erasing things? Either restore the tab functionality, or just don't let it reverse and erase.
Before pressing the Tab key, make sure the text is not highlighted. When indenting the text, place the cursor in-front of the paragraph, and press Tab.
