Preview version doesn't match solidworks version.

I am having a problem with drawings that are opened withe-drawings, SWveiwer, or even looked at in the PDMWorks previewwindow not matching when actually opening the file in Solidworks. Ihave tried clearing cache, checking out file again and re-savingbut the problem still exists. From what I can tell, if I do a saveas on a part and drawing the preview will show the original partand not the new. But it has also been happening on new partsshowing a older version in the preview.

Anyone have any suggestions?
