We are currently running Win 2K, SW 2004 Sp 2.1 and are experience random multiple entities being displayed and printed. It occurs when files are viewed either through SW or with SW Viewer. These 'corrupt' files when viewed from non-Solidworks PCs result in the same issues. I worked around this by performing a Save-As on both the model and drawing documents. But this is a pain.
We have also observed some processing slow downs. Switching to software open GL improved the speed, but obviously doesn't utilize the graphics card.
These two items together make me suspicious that it is related to a graphics card driver issue. But because it is also displayed from other non-Solidworks PCs indicates the double entities are resident in the drawing file. The multiple entities have been dimensions, centerlines, bolt circles, etc.
Suggestions appreciated.
