You can maybe make things better by rebuilding the help index files.

Open a command prompt, and navigate to your $(BDS)\Help\Doc folder. Run H2Reg -u to unregister the existing help topics, and then run H2Reg -r to re-register. THen launch help, and you should get the dialog that says it's indexing content.

If you want more info about H2Reg.exe, simply run it without parameters from the command line; it will display a dialog with details about the command line switches and what they do. You should also scan throuh H2Reg.ini, as it has comments on each section and what it does to affect things.

And, as an aside, the help in XE is vastly improved, although it still has a way to go.
