RH9 in TFS Crashes When Trying to Add an Index Keyword to a Topic
I am using RH 9 with TFS (Visual Studio 2010) on a Windows 7 64 bit system.
My project is checked in to TFS and is running well.
However, when I add an index keyword to a topic (Topic Properties > Index tab), and click Apply, RoboHelp crashes.
I get the following error:

I have other writers using RH and TFS and they don't experience this problem.
Has anyone seen this before and any ideas how we can solve this?
Any help would be much appreciated.
Thanks,
Mack
