The ghelp widget under windows is a bit broken, as it expects the help files to
be in a format that isn't typically installed under windows. I need to add in
some windows-specific code to handle cfm(?) filea. Currently the basic code is:

helpFile = help(topic, package=force(pkg), verbose=TRUE)[1]
text = readLines(helpFile)


where pkg and topic are passed in and "text" gets processed then displayed. I
think I can easily crib the windows code from some source, so I'll see what I
can do about adding this feature with the next release. --John
