Missing line segments when saving as DWG

When saving a SolidWorks drawing to a DWG file, my systemsometimes leaves out small line segments in the DWG file. Formonths, the conversion worked fine. Later, it failed consistently,leaving out line segments especially on parts of text elements(sketches made with the text tool, then cut-extruded into amaterial). This behavior completely stopped my workflow for severalweeks (which requires the DWG conversion), and now it's workingagain. I don't know why!

If anyone has suggestions as to how/why this happens, I'd reallyappreciate some feedback. I can tell you this:

1. I'm working with SolidWorks 2006-2007 Academic Edition
2. I doubt it's the files. When opened in a newer version ofSolidWorks, the conversion works fine. These same files worked finepreviously on the original system too.
3. I tried reinstalling SolidWorks and this didn't fix the problem.

Your thoughts?
