Web links not showing in 8.51 FP2

We just upgraded half of our (all 64 bit Win 2003) virtual servers from 8.50FP1 to 8.51FP2. This seems to have caused a new issue. Web links in two replicas show up differently when using iNotes. The links show up as expected when viewing the memo on the older version server, but on the FP2 server the links just show up as text HTML code and cannot be clicked. This seems to have been introduced by this upgrade. We have thousands of users effected by this problem. Any help would be appreciated.

Subject: Passthru HTML blocked by default

The cause of this problem was a decision made by someone at IBM to block passthru HTML by default starting in Notes version 8.51. To allow passthru HTML you have to set the NOTES.INI variable:

iNotes_WA_AllowPassThruHtml=1

and restart the server. Poor decision to implement this as being blocked by default in a .01 release. Wouldn’t it have been better to provide the ability to block passthru HTML by using a NOTES.INI variable should it be deemed necessary so as to not disable existing code? We had a custom application with OVER TEN THOUSAND users disabled for days because of this.
