vertices dot not showing as circle

Hello,

I am running 3DS Max 2009 and I have been struggling with vertices not showing as circles. my system is Windows 11 and VGA is Nivida 2080.
I have tried everything that I can think of but nothing works if I click the show vertices as circles they show but as soon as I move around the screen or move the mouse they disappear. I have tried the compatibility setting and that didn't work.
so please if anyone can help me with this matter that would be great.

see the attached screenshots
1 when I first open max and create the sphere
2. after going to the edit poly
3. when I go to change the size it sphere but as soon as I move the chape they disappear.

thank you for everything gentlemen.
