Just got back and seen your post Wojtek. I'll have a go at that tomorrow, as I've got to get some sleep - I've been on the go for about 36 hours now i think!! It's strange that Windows and IE works on everything else though, even if a little slow at times. I think I'll have my PC checked over, but meanwhile, I've installed Firefox, and I'm getting somewhere, I think!
Now, I get a long, open box on any post with attachments, headed 'Attached Images', but with nothing else in the box. But, if I clear the recent history, the icons for the images then appear. However, if I click on these, a flash screen comes up saying I'm not logged in, even though I've clicked the 'Remember Me' box. So, I log in again, and then Ican view the images. But, I can't get back, because if I click on the 'back' button, it takes me back to the log in box! I then have to scroll to the top of the page, and click on 'Warbird Forums', in order to get to wherever I want to go!
But, I'm too tired now to do any more, or I'll make too many mistakes. So, I'm going to log out, then clear the history, cookies etc, and switch off and see what happens tomorrow.
I'll probably shouting for help I think!!
