Zoom in sketch 2001

[chapers]

When editing a sketch by zooming in, the line entities disapear leaving only the dimensions and dimesion lines visible.If I scroll the pointer across the screen where the lines should be the lines re-apear one by one.
There are no problems when zooming on the model.
I am running XP Professional,MSI Geforce4 MX440se 64mb ddr
512 mb ram Pentium 4 2.4Ghz.

Thank you for any thoughts.

Fairly typical GeForce/SW/XP phenomenon. Make sure you have installed the latest driver downloaded from the nVidia website. If you are using the default driver from WindowsXP, there will be trouble. Also, try toggling the "Use Software OpenGL" checkbox at the bottom of the options form under System Options:erformance
