problem with displaying index in RH11

Hi,

I’m using RH11 to make Responsive HTML5 output in 4 different help projects, with the Theme2-_Government layout (in Dutch and French).

All projects start correctly with the TOC pane open and the whole indexfile displayed. Even my first indexsearch is OK.

However, no respons with the second index search, because the program keeps loading, and loading… the index-entrys.

All 4 projects have the same problem.

What's going on? Thanks for your help!

Paul
