sw2009 and winvista and win7 64 bit

I run SW2009 sp4 on both systems: Win7 and Win Vista - (64 bits)

I have no complaints so far -  both run very smooth

The only problem I have so far is the SW crashed each time I did something related to adding drafts or perfoming draft analysis

Anyone here has experienced about this behavior???

Thx
