I have a problem with font in PowerPoint 2010. I work in Telecommunication firm and I have to use Tele Grotesk Nor font when doing presentations. When I have one presentation opened (in Tele Grotesk font) and if I open another one (with another font, e.g. Calibri), the first one will overtake the font of the second one. If I close the second one, font of the first one returns to normal (preset font – Tele Grotesk Nor). Also, if I send my presentation with Tele Grotesk Nor font to anyone else in my firm they will get a presentation with totally different font (although we have the same version of PowerPoint and although they also have that font in their MS office). And this happens to all of us in the department, not only me. I embedded font of my presentation but that did not help. I do not know if the problem is in Tele Grotesk Nor font, or in PowerPoint, but I would really appreciate if you have a solution for my problem!
