Text partially masked from view

Hi,

When I use dimensions part of the dimension text is being masked from view. I can’t find any way to correct or adjust this. When printed to PDF the text appears fully. The problem exists within the model before printing.
Any thoughts?

This user fixed his problem with a Windows update:

Thanks John.

Judging by how slow the PC was to startup this morning, I think windows must have updated last night.
I have checked the text problem and it appears to be OK.
