I have been having terrible problems with Photobucket Pupps, so it's not just you. At one stage I thought it was my PC causing problems, then I got an error message which I Googled and apparently it's a known problem which stops the right click of the mouse working. Only a re-boot seems to stop it for a while. Nobody knows the cure either.
The HTML code stopped working for me too last week when Flash Player did an update when I switched on - I also searched for that problem and found others having the same experience.
The only way I can post a picture from Photobucket is to double click on a picture so that it comes up large size, then highlight it to copy and then I can paste it. But it's a bit of a palaver to say the least. Somebody somewhere has got it in for us!!!!
