I am doing an upload using IE8 on Windows 7 RC. When the software that is used to upload gives the pop-up to select the file that has to be uploaded, there is a new error dialog box that comes up. The error dialog box states that the browser is hung and do you want to close or restart the browser. If I do not respond to that error dialog box it just goes off when the upload is complete. Has anyone else seen such an issue? This does not happen on every Win 7 machine that I have. It is happening on only some(all Virtual Machines definitely) and wherever it happens, it happens consistently.
