I tried different combinations of deactivating and deleting Helvetica and Helvetica Neue, but the problem still hasn't been solved. I'm almost out of ideas and ready to reinstall 10.6.7. Too bad because I've noticed some improvements with 10.6.8.

According to Kurt Lang, H and H Neue are required by the system, but I followed his advice on how to delete them without the system recreating them. Quite elaborate. Nothing helped.

I said before the font problem affects the system display and not display in applications. I'm not sure about that anymore. I am sure that the font smoothing option under Apperance doesn't do anything.

Well, I've just about had it with this one. You know, I had this monitor replaced by some local guys when it had a bad pixel. Maybe they did something to it.
