Example .doc (Word 97-2003) with embedded MathType objects

Writer's handling of it's inability to edit a MathType OLE Object in a Word 97-2003 .doc file isn't very intuitive or user-friendly.

The attached example file gives two embedded equations, identified as "MathType Equation" and "MathType 4.0 Equation" in Word 97. (I couldn't find any way of identifying them in Writer.)

Attempting to edit the first one in Writer by double-clicking on it opens a read-only .tmp file in another Writer window, containing some of the characters used in the equation, but none of the formatting. It is not possible to edit the equation.

Attempting to edit the latter (4.0 type) in Writer results in a dialog box with a red cross icon, and the text "General Error".

This is a lot less helpful to a user than the behaviour in Word, where it is simply explained in a dialog box that it cannot edit the equation.

LO RC4 Ubuntu 10.04 x86

In my case first formula behavior is equal to described by dave_james. When trying to edit second formula it just highlited, without any warning or appearing other windows.
Comment 2 Jaxson Lee 2011-01-28 16:37:20 UTC
Just tried it myself on Ubuntu 10.10 x86 LibreOffice 3.3.0 OOO330m19 (Build:6) tag libreoffice-3.3.0.4, Ubuntu package 1:3.3.0-1maverick1 and got the same for the second object as I did in Windows, the General Error dialog box.
Comment 3 Lior Kaplan 2011-11-26 14:26:11 UTC
With LibO 3.4.4 I get the same behavior in the example document. On another document I got, LibO fails to edit a "MathType 6.0 Equation" OLE in a doc file, and shows the general error popup for the same document in docx format.

Double-clicking on either one on Ubuntu, nothing happens.

Some debug output:

warn:oox.storage:3835:1:oox/source/helper/zipstorage.cxx:67: ZipStorage::ZipStorage exception opening input storage: 
VisioDocument: version 0
Found xml parser severity error Document is empty

On Windows I happened to have MathType installed and it opened correctly for each formula.

Seems like LO supports MathType up to v.3 or v3.1 or v.3.5. I didn't find a bug asking for MathType 4+ support, so I rename this one.

Comment 13 Roman Kuznetsov 2018-07-24 18:14:23 UTC
double click on first OLE object -> Writer crashes (see bug 118919)
double click on second OLE object -> window with General error.

still repro in

Attempting to edit the formulas by double-clicking simply results in nothing happens.
The formulas feel like they are getting treated like images.
Comment 15 Buovjaga 2018-10-09 13:01:41 UTC
With attachment 53915 [details], double-clicking either formula on Windows gives General OLE error. On Linux it opens my image editor (but does not display anything.
In my comment 9 I say having MathType installed would make it open the file in it.

Yes, please contact them, if you have time.
