what happens if you hold shift while you start Thunderbird (Click the continue button)

I can receive emails but when I try ti write a new one or reply or forward existing emails, the usual screen does not open. Instead a small window opens in the small task bar at the bottom of my screen in Thunderbird and whilst I can hover over them to see them no amount of clicking will bring them on to the full size to use. I am on Windoes 8.1

Thanks for your quick reply but although it did not solve my problem, I found that other functions were not working this morning and after a good deal of head scratching I found out that it was the remote Microsoft keyboard attached to my laptop which was causing all problems! It was only a few months old but I have now bought another but Advent this time and all is back to normal. Thanks once again. Conway Hall
