Before you pour your life's work into a CPPWebBrowser-based application, 
please bear in mind that it is just a wrapper for IE7, and, as such, is 
bound to the limitations of IE's architecture. This may not seem a problem, 
until you push the Javascript engine beyond its limits, which is 
surprisingly easy to do.

A case in point is my Hangman page at http://jacobsm.com/hangman.htm (about 
2.5 MB in size). It uses words from a special dictionary file I pieced 
together with over 108,500 words. The sheer size of the words array created 
when the page loads under IE7, causes a stupid message about the awds array 
not existing, despite having just been declared. Loading the same page under 
Opera 9.10 works exactly how it should, with no errors, and a great game of 
Hangman going!

To sum up, IE7 is significantly inferior to Opera 9.10 in certain areas, so 
any CPPWebBrowser-based application based on it, will also be inferior in 
those same areas.
