NAV 2009 (sp1) displays static fields sometimes in bold font

BenOostdam

Hello Guys,
I'm experiencing a rather strange issue on views and forms, regarding the display of static fields.
Rather random, some fields are displayed with a bold font, that I cannot explain.
This seem to happen when the classic client in running on W2K8R2 machines only.
Whenever I click with the mouse on the bold text, it's getting even bolder.
Nothing changed on the server side. I tried upgradinging to the latest client build version without any improvement.
Anyone a clue? I'm seriously confused, and don't know what to investigate as a next step.
Please contact me, a post a suggestion here.
Thanks in advance.
