Some Signs in LibreOffice Math are displayed wrong

Hello everybody,

I`m using LibreOffice 4.4.0.3 on a Win7 (64 bit) Professional Service Pack 1 engine.

As i want to create some formulas I’ve got the problem, that some signs like “=” are displayed wrong. I’m pretty sure, this is due to a missmatch between the code used for the signs in LibreOffice and Win7. But i could not find a way to fix it. It seem’s that these false signs are used out of windings as they are displayed as postboxes, arrows and postcards for instance.

Has anyone a hind for me how to fix this?

Thanks!

Problem solved…
