I just tested Employee Care using the Default without modification and it is working correctly. If you get the same, it suggests the problem is with modifications, even though they were working in RoboHelp 11.
It might be worth deleting the CPD file and reopening RoboHelp.
If not, try creating a new layout in your project and see if that works using Default unmodified.
Let us know what you find.
See www.grainge.org for free RoboHelp and Authoring information.

You where right. It was the modifications that did not work well i RH2017. I had to do some more modifications in the file whskin_tbars.htm and now it works well again.
