Dear kmgp,
thanks for your suggestions. I will try them shortly. In these weeks I almost gave up to it. But I will give it a go again: I never tried the settings you saggest.
So you Thinapped MS Word and MathType separately, not together. My fear is that in this way one misses the integrated menu that Mathtype adds to the Word standard menu. I hope to be wrong. In any case is not possible to thinapp both of them with a single snapshot (this is what I was trying to do)?
Thanks again.
Update:
I tried your method. Here my results, after uninstalling MT from the system and using just the thinapped one as you suggested:
1. the MT addon menu is properly shown in Word 2003.
2. The equation are created ok in the docs. In my case in Insert/Objects.... I do not have obviously MathType as possible OLE choice, since Word was thinapped before installing and thinapping MT. But the creation works even if one choses just Microsoft Equation 3.0 (MT is its substitute and launches properly).
3. Insead if I attempt to edit an MT equation I have often the warning shown below. This was the type of problem I had before asking help here (i.e. no MT edit)
I wonder if other tweakings are needed in the package.ini or if one needs to install first MT --> thinapped it; and then Word --> thinapped it. Above I did the opposite.
