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... =E2=80=9Cregsvr32 msflxgrd.ocx" from a command prompt you should get a verification if it is successful
(props to Mike =E3=83=9E=E3=82=A4=E3=82=B1=E3=83=AB for the tip)
