I don't think so. I've tested this with two standard user accounts (and old one and a new one) as well as my own admin account. Same bug manifests in IE for all accounts. No bug manifests when using any other browser with any other account. No problem with posting to existing threads or creating new threads. But the user gets signed out when they try to upload a list if they didn't check the "Remember Me?" box when they signed in. This is definitely an IE related bug in LDM or at least a problem with my installation.

If you are using LDM then try it yourself. Sign into your forum using IE8 without checking the "Remember Me?" box and see what happens when you submit a file for upload. If you don't experience the bug then it's something wrong with my installation. If you do then it's a bug in LDM (or something wrong with both of our installations - which seems an unlikely coincidence).
