Why does IE shut down while on certain sites?

I have about several users who go to a site,

Before it shuts down it will give the Internet Explorer window which reads: Internet Explorer has encountered a problem and needs to close. We are sorry for the inconvenience.

When I click the link (click here) which allows to reads the report, it reads:

Error Signature:

AppName: iexplore.exe AppVer: 6.0.2900.2180 ModName: jscript.dll
ModVer: 5.6.0.8831 Offset: 00011d84

Any ideas? Anyone?
