Sometimes Internet Explorer "decides" to remember the wrong size for a new window. Whatever you do, you can't seem to get it to remember a normal size. To fix this problem, simply follow these steps:
1. Click on the Start button and select Run 2. Type in 'regedit' and click OK 3. Look for this key: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main 4. In the right pane delete the 'Window_Placement' key 5. Click Yes and exit the Registry Editor
