OK I pretty much know I should know the answer to this myself, and I'm pretty sure it's a browser problem not a photo.net problem but.... Just recently (maybe within the last week) when I make a post, but use the "back" button to correct an error before I confirm the posting I get an error message telling the the page has expired and for my own good IE6 won't display the info. The puzzle is that IE6 didn't use to do this on photo.net. I could back up, correct my text and then proceed. So while I'm pretty sure this has nothing to do with photo.net I'm at a loss to explain why it suddently started to happen in the last week or so. I haven't played with the IE6 settings as far as I know. I don't think MS have secretly updated my browser (though anything is possible with those guys). It;s possible I've updated or installed some new software (latest demo version of neatimage, maybe breezebrowser) but I don't know when it started doing this and how that relates to the time of any software installation. You wouldn't think installing other software would make IE6 change, but it is MS software and anything is possible I guess. I know this problem has been mentioned before, but does anyone have a clue why it happens and is there anything that can be done about it?
