I had/have the exact same problem.
I got this info from RSI. It worked for me (but of course a windows update
made the problem come back. ARGH!)
Here is the solution:
In ENVI 4.0 on Windows 2000 and XP, some customers may see a blank page
using the 'Index' tab of the online help. This is most likely due to a
problem with a particular version of a file associated with the HTML help
system. This Tech Tip article discusses the potential source for the problem
and suggests a workaround.
The hhctrl.ocx versions that may have problems are: 5.2.3735.1 and
5.2.3735.0
This is HTML Help version 1.4c, which is the most recent version as of
January 2003.
The hhctrl.ocx versions that appear to fix the problem are: 5.2.3669.0 or
5.2.3664.0
* 5.2.3669.0 is HTML Help version 1.4a
*
* 5.2.3664.0 is HTML Help version 1.40
To check and see what version of HTML help is running on your system, please
browse to your hhctrl.ocx file. This file is usually located in the
C:\WINNT\system32 folder. Locate the hhctrl.ocx file, right click on it, and
view Properties. Click on the "Version" tab.
At the Microsoft HTML Help website:
http://msdn.microsoft.com/library/default.asp?url=/library/e n-us/htmlhelp/ht
ml/hwMicrosoftHTMLHelpDownloads.asp
You can download their latest version, which is 1.40. This may fix the
problem.
If you have the newer version, you can uninstall the current one, and
reinstall the older version by doing the following:
1. Open a DOS Command Prompt: Start->Run->cmd
2. Unregister hhctrl.ocx in winnt\system32 at command prompt:
cd \winnt\system32
regsvr32 /u hhctrl.ocx
3. Copy over the old hhctrl.ocx
4. Register hhctrl.ocx:
regsvr32 hhctrl.ocx
