(Yes, I downloaded the latest version...) OK, I actually discovered the solution to this problem by accident when trying to correct a blue screen of death (windows stop) error that came up on my computer. A little history... originally I couldn't see anything in MED or WED. No grid lines or anything. When I tried to create a cube or something nothing would happen. Then I discovered by switching to an older driver dll with File->Preferences->Video Out I could see grid lines again and all was well. Later on I came across this problem where I noticed I couldn't see vertex points and therefore posted this question. Then today I got a blue screen while working on a model in MED. It said an error occurred with the ialmrnt5 driver. After investigating this I realized my video driver was rather old and that others had indicated seeing this blue screen when working with 3D graphics applications using my driver. The recommendation was to upgrade to the latest video driver. So, I did this and afterward I realized I could switch my File->Preferences->Video Out back to what it was initially set to by default (the latest driver dll). After updating my video driver and setting this dll driver option in MED and WED to the latest one I could finally see the yellow vertex points!

Thanks for your help...
