I don't know if this is the correct forum; I really don't know where to look for help. I just noticed that with several programs (MS Word, a flow chart program, and a Cad program, but not MS Paint) I cannot draw a line from a right staring point straight to the left. It will just not appear! To be more complete, in any of these programs, I can click the mouse to set the anchor point for a line, while still pressing the mouse button, drag the pointer to draw the line, then while still holding the button down, drag the pointer 360 degrees aroud the start point. The line will correctly be rendered, like a watch hand around the dial, but the line goes blank a the 9 o'clock position! It will continue to appear when I pass 9 o'clock. Since it happens on multiple programs, it must be something they have in common, a DLL?, the video board? I don't have a clue. Help!!!
