Thanks for the link. It works for IE but not for Windows Explorer.
I'm sorry I didn't make it clear. When I open Windows Explorer it opens at a size equal to the settings of Internet Explorer. I can alter the size of Windows Explorer with the drag function as you suggest but when I close and re-open the window it reverts to whatever size the Internet Explorer window was last set.
If I alter Internet Explorer's window by dragging and then close the window. Windows Explorer will open at that size not how I closed it last time. I'm beginning to wonder if the Freeserve software has altered a setting.
Thank you both for your interest.
