I have created the .chm file OK, but the 'search' isn't working?
There are two possibilities:
The operation is screwed up, delete the files in the webpages/Temp folder, re-PROCESS all your documents and BUILD.
or
There is a problem with the Windows itircl.dll, either you haven't got it or it isn't installed properly.
You should re-install EasyHTML/Help then re-install the latest version of Internet Explorer.
