Re-sizing vertex points?

I work at quite a high resolution, and I need to enlarge the actual vertex points as they are seen in the 3d viewports. I’ve scoured the user prefs, with no luck. Any ideas, anyone?

It’s in User prefs->Themes, the Background Color menu. In 2.46 it’s the bottom menu in the second column, probably says “Background.”

Wow that was fast! Thanks CD38 - I’ll have a poke around…

Here ya go…
