Hi, I am using Outlook online, FF 46.0, Win7 64 bit, and I have the following problem. When I compose a message and click anywhere in the text field to see the cursor blinking, I can move the cursor with arrow keys but not with Page Up and Down keys. When I press Page Up or Down, the cursor disappears and I scroll the page as if clicked outside of the text field. This doesn't happen on other sites, e.g., now as I type here, so I realize this might be an OWA problem. On the other hand, it doesn't happen in OWA when I use Chrome, so there might be something I can do with FF perhaps. Would appreciate any advice. Thanks, Adam
