We were crashing newly built PC's with the same OS & SWX admin images installed as typical, but the Helix and Feature Library functions caused SWX to crash (2006 & 2007). Solution- Regsiter the MsFlexGrid control... “regsvr32 msflxgrd.ocx" from a command prompt you should get a verification if it is successful (props to Mike マイケル for the tip)
