When you try to move or resize a window on a Microsoft Windows Server 2003 Service Pack 1-based or Microsoft Windows XP Service Pack 2-based computer, you may receive an error message that is similar to the following:
This problem occurs when you use a drag operation to move or to resize a Microsoft Internet Explorer window or the window of another application.
You experience this issue if a script in the Web page that is displayed is performing either a windows.resizeTo method or a windows.moveTo method when you try to move or resize the window. This issue occurs because of a design change in Windows Server 2003 Service Pack 1 (SP1) and Windows XP Service Pack 2 (SP2). This design change improves the security on the computer by blocking any move or resize functions.
Windows blocks these functions by using a script when the mouse button is down. If the mouse button is down, Windows considers the operation to be a drag operation and blocks any move or resize functions. This behavior helps prevent an attacker from transferring malicious files to the computer.
To work around this issue, use a WebBrowser control-based application. When you host the Internet Explorer Web Object Control (WebOC), you can use the IHTMLWindow2::resizeTo method or the IHTMLWindow2::moveTo method to resize the window.
