    Problem with Equation Editor

    When I double-click or right-click an existing equation object, Word displays the error message "Word cannot edit the Microsoft Equation 3.0". If I insert a new equation and starts entering the equation in the editor, it gives a GPF-like error message "This program has performed an illegal operation and will be shut down".
    This problem appears on my home computer running Windows 98 and Office 97 SR-2. This problem does not occur on my work computers with the same documents, running Windows NT 4.0 (SR6) or Windows 2000, Office 97 SR-2.

    There is a KB article Q183195 that seems to adress this problem, but neither of the two suggested workarounds solve the problem.

    Thats when I turn the problem over to the renowned specialists in the lounge ;=)

    Ensure that you are saving these files as Office 97 and not as 95 files. If you must save down, save as BOTH 95/97 documents. Not sure this will correct your problem either.

    Thanks for the tip, but regretfully it doesn't apply in this case. The same document that cause trouble at my home computer works well at my work computer, both running exactly the same version of Word.

    Anyone having another suggestion?

    Thanks!

    Re: Problem with Equation Editor

    Hi Steen:

    Q183195 addresses a different issue than "illegal operation". I only have the usual steps that I use when I don't know what else to do. Try em one at a time.

    1. Make sure all other programs aren't running (ctrl+alt+del & end task).

    2. Rename normal.dot to abnormal.dot & start Word. If this helped, you had a corrupt normal.dot.

    3. Go to Start/Run & type: <font color=red>winword.exe /a</font color=red>
    This starts Word with a new normal.dot & NO add-ins. If this cures the problem, remove add-ins one at a time from the Word startup group.

    Good luck.

    [img]/w3timages/icons/grin.gif[/img] Problem solved! The problem was caused by missing definition of fonts for the different styles in Equation Editor. How the definition of the fonts have been lost I don't know, but I will leave that mystery for later.
    Problem and solution is described in KB article Q167958
