### [Solved] Math formula editor frezees after upgrading to 3.5

Posted:

**Wed Feb 15, 2012 2:59 pm**I upgraded today to release 3.5, from 3.4.5 on a windows 7 notebook. Since then Math formula editor is not working anymore.

Steps to reproduce:

1. open a writer document, new or existing

2. insert a Math formula object anywhere

3. The grey rectangle that should contain the equation on the page appears, and menus are transformed into those relevant to equation editor.

However, the subwindow that should appear on the screen below the document, in which you enter and edit the equation code, does NOT appear anymore, and nothing

(numbers, letters symbols, whatever) can be inserted in the equation, even using the special objects window. You can see the objects windows, but when you

click on any object (e.g. a sum or an integral symbol) nothing happens. It is the same with the Greek letter insertion window.

WHAT IS WORSE, after uninstalling 3.5 and reverting back to 3.4.5, the math equation editor REMAINS BROKEN!!! It behaves exactly as described.

If you work in a context where you write many math equations, this means that Libreoffice is COMPLETELY UNUSABLE.

Alas I had no choice but to revert to Openoffice 3.3.

Notice that:

- until this morning, with any version of Libreoffice, I never experienced this problem

- if you open a math equation editor directly, instead of one embedded in writer, it is unusable just the same.

- If I run Libreoffice portable 3.3 from an USB memory stick, the math equation editor works fine, so I think it is not a hardware problem of my PC.

Any hint to what has gone horribly wrong would be greatly appreciated.... thank you.
