When you try to open multiple modal dialog boxes in Internet Explorer, or in Mshta.exe (an HTML program), you may receive a stack overflow error message.
This problem may occur if the number of modal dialog boxes exceeds the amount of memory (the stack file) that is permitted for modal dialog boxes.
This problem may occur more frequently in Mshta.exe because the stack file in Mshta.exe is smaller than the stack file in Internet Explorer.

To work around this problem, reduce the number of modal dialog boxes that are open at the same time. Follow the prompt in each of the modal dialog boxes to close them.
Microsoft has confirmed that this is a problem in Microsoft Internet Explorer 6.
Modal dialog boxes are message boxes that must be closed before you can continue working in the program where the modal dialog box appears. Frequently, a modal dialog box displays an error or alert message.
Note The hotfix that is provided in the "Resolution" section of this article increases the size of the stack file in Mshta.exe. However, the hotfix does not increase the size of the stack file in Internet Explorer. This problem may continue to occur after you apply this hotfix, but the hotfix reduces the frequency of this problem.
