I have a question about my site in IE7. When I click the browser's back button, it returns to a page which is normally centred in the window (using margin-left:auto and margin-right:auto) but it's now jumped to the left edge of the window. Its really weird! If you then reload the page, it goes back to the middle.
It also happens after you submit a form which opens in another window - the original page is reloaded by submitting and it has jumped to the left.
Only happens in IE (tested in v7). Doesn't happen all the time, only with some pages (which seem to be the same as the others).
I'm using VB C# ASP .NET v3.5 to handle the form submission.
Please help if you have any suggestions.
