I was in Yahoo mail. I was getting ready to print. The print dialog was open already. Then I got some kind of notice from Firefox that it needed to restart to install an update. No problem I thought, the updates have always had no problem. Since I already had the print dialog open, I clicked print. No print. Checked the printer queue - nothing in it. I thought well, Firefox might be holding the print since it was asking me if I wanted to restart. I closed the print dialog and hit update. Of course, FF got stuck during an update (first time). Update Failed. Tried again, and it worked, but now I can't print. I can hit control-p and File - Print and use print preview. Hey, wait a minute - I just noticed that if I just hit print, it will print. However, I never do this. It appears that Firefox is refusing to open the print properties for any print device (not just the default). Either that or it somehow heard the 'hit print' HP marketing slogan and took it to heart (i.e. I can literally only hit print, ha ha). I have a feeling it has to do with the print dialog being open during a restart to update prompt.
