Hi Brent,

Is it possible to replace a DLL used by the compiled WebKit with a  
newer version of the same DLL without recompiling WebKit?  I need to  
link my application with CFLite but your compiled version of WebKit in  
CallJS does not include a CFLite library file (only a DLL).  Your  
requirements package has a DLL and a library file though.  Can I just  
delete the DLL without a library file and copy in the one from CallJS  
or will that not work?  If not, would you be willing to build me a  
copy of WebKit with the CFLite library file intact?  I would be  
willing to pay if necessary.  I have tried extensively to build the  
source, but I always get errors that I think are related to using  
Visual Studio 2005 Express.  Would buying Visual Studio 2005 Pro make  
building WebKit work more seamlessly? I'm not sure I would have much  
use for it other than building WebKit, so I would rather not buy it if  
I don't have to.
