As of 6/14/2011 Microsoft released a critical update (KB2530548) for Internet Explorer 9 that addresses the issue stated below, and manually adding a registry key may no longer be required.
Also, PaperVision Enterprise version R75 no longer requires this registry change.
When a user attempts to use PaperVision Enterprise ActiveX controls, such as the document viewer, workflow viewer, and administrative controls, Internet Explorer 9 appears to lock up and can only be closed via Task Manager.
Enabling extended Full-Text search options will display the following options when executing a full-text search: Variable Term Weighting; Stemming; Phonic; Fuzzy and Synonym Searching. NOTE: refer to the PaperVision Enterprise User Guide for more information regarding each of the options listed above.
If a project in PaperVision Enterprise has too many index fields, users will have to scroll down to see all of the fields when performing a search in the thin client. There is a way to modify one of the CSS (Cascading Style Sheet) files to show all of the index fields at one time, and eliminate the scrollbar.
