IE7.0 csh htm# run command

I have searched vigorously, but must be asking the wrong question. We have hundreds of applications with a command like: help.htm#context_sensitive_position.htm that worked fine under IE6.0 but IE7.0 strips the trailing command. Is there a setting in IE7.0 that will allow it to perform like IE6.0, or is there a new run command that IE7.0 will accept to refer content along with the default page

Thanks in advance.
