On the OPAC detail page there are some inconsistencies as to when the browse controls will appear. To recreate: -Have OpacBrowseResults turned on -DO a search that will turn multiple results -Click on one of those results and see the browse controls -Click 'place a hold' and then use your browser's back function -Browse results are gone This doesn't happen to me on the staff side. Looking at opac-detail.pl it seems the busc param is not getting passed into the template when you press back in your browser.
Does the "busc" session param get reset when the user logs in?
