ahh just checked your other post, think you are using radeon 7500 pro, pls ignore my question hehe
but thanks again

thanks for advice, tariqrf.
i tried latest driver, version 43.45, but problem remains the same. Which model is your radeon card? I may want to try a 9700 pro ;)

Has anyone experienced some lines displaying problems in Maya like me?
I get disappearing normal lines while I am moving vertices. I also get some of the selected edge lines not turning orange on...
