SW 2009 CRASHES WHEN CHANGING REFERENCES IN DRAWINGS

i have a bunch of parts that are very similar and in th epasti have been able to copy ht edrawing, rename it, and when openingit, change references to point to the new part. this way, most ofthe annotations come a cross and i do not have to re dimensionthings.

HOWEVER, in SW2009, whenever i try this, the freaking thingcrashes!!! has anyone else ecperience this? oit crashes at least 9out of 10 times when trying this

worked fine in 2008.....SolidworksDrawings And Detailing
