I have updated to WebCore 1.4.0 and now there is an error on the TWebHttpRequest component. The signature of the RequestReponse handler has not changed, but the compiler now gives this message if a handler is in place. It compiles ok without a handler.
[Error] fWebMod.pas(1): Incompatible type arg no. 2: Got "TJSXMLHttpRequestRecord", expected "TJSXMLHttpRequest"
