CAUSE

Identifiers for controls in a custom dialog box must be unique.

WORKAROUND

To work around this problem, if you run a Word 2.x macro in Word 6.0 or later that contains duplicate dialog box identifiers, you must edit the macro and remove or modify one of the identifiers.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Word 2.x, which should also only have allowed unique identifiers. This problem was corrected in later versions of Microsoft Word.
