Why I can't draw simple line

Hi I am also facing the exact same problem. Can anybody please elaborate the method to make it normal? I am using v8i SELECT series 10

Thanks 

It is not file dependent but it is graphics glitch with know bad graphics drivers. Set QV_D3DVERSION = 9 and it will go away but it is not recommended for intensive 3D use.

Hi Oto, where to set this code, please let me know in detail. I am a novice microstattion user. Thank you. 

QV_D3DVERSION is a configuration variable, and can be found in the "Configuration..." dialog from the "Workspace" menu. That dialog has, on the left-hand side, and option to see all configuration variables alphabetically. If the variable isn't in the list, you can create it with the "New..." button. This opens a dialog where you can enter the Variable name (QV_D3DVERSION) in the top space and the value (9) in the next space for New Value. Click OK to store the variable, and use the File -> Save menu item in the Configuration dialog to save the changes to your configuration file.
