Comment 3 for bug 33628

Yes, in the version before the recent upgrade the minus sign also pushed against the "b" and sometimes it wasn't even displayed. That's pretty annoying. Worst thing is that the new version introduces this bug where the minus sign isn't even displayed any longer.
The package msttcorefonts has been installed for a few weeks now and the problem seems to occur with every font. So I don't think that it is msttcorefonts' fault.
I hope someone fixes this bug since I have absolutely no idea what's causing it and this bug makes me stick to Windows for a while because I have to write some documents with formulas. It must have to do with some recent upgrades.
