Text changes to squares depending on zoom

[JR_11037531]

When zooming in Creo Parametric 10.0.5 the text turns into squares. The more I zoom in the more characters turn into squares. Collegues do not have this problem. How do i fix this?

I haven't seen this directly but we have long had an issue where sometimes in a drawing, some of the symbols end up printing as a square. The answer in those cases is to go into the detail options and checking the symbol_font setting. We get squares when they are set to Legacy, so we set them to Stroked_ASME because we don't use a True-Type font and if we just used ASME the symbols come out bold compared to our other text. If you use a TTF then you might want to set it to ASME. If you are outside the U.S. then you probably would use Stroked_ISO or ISO.
