Thanks for the replt Rev, thing is, the problem seems to have fixed itself.

I first tried running SFC & reinstalling the ie.inf file & restarting but that had no effect on the problem what so ever. I finally decided as I had a feeling it was maybe caught in a loop because it couldn't find a file, that I would try to use Sysinternals FileMon to try & see if I could find the problem. Suddenly noticed a few things running in the background which shouldn't have been, tried then download something & the same problem occured and it just appeared to be stuck, so I just left it for a while, and then up popped the save dialog, so decided to continue and now everything seems to be working fine, even though I actually tried nothing at all.

Coffee.
