Answer 1

it is really strange, that was what i got in netbeans 6.0, now in version 5.5.1, i get no errors, except the program doesnt load a webpage like its supposed to... (when i click the go button, the WebBrowser Area disapears)
if you look at the picture you see how it is set up, i dont know if i somehow need to import everything in JDIC? (the IEembed.exe, dll files, ect)?
