Hi there, Have been a happy Thunderbird user for years. Have always been able to right click on a file ~ Choose send to mail recipient and TB would open a new message with file attached ....All was good. Recently things have changed: Now if I click on file with TB open nothing happens. If TB is closed it opens TB but not a new message. When it first happened a window popped up that said something about being used by another program (sorry, I did not save a screen shot or write down). There was a checked box that said always show this message when this happens. So, not being very smart, I unchecked the box and now the message does not pop up but the problem remains. I did some noodling around on Google but have not found anything simple enough that I was comfortable doing it....Most involved regedit and I am not really comfortable in there. The only thing that has changed recently is that Windows wanted to do an update and I allowed. That might have caused this but I don't know. So anyway.....Any of you folks hear of this and do you have any suggestions?

Thanks in advance! RC
