@all, I had just installed Visual Studio in a machine that has Dreamweaver. Apparently, Dreamweaver fails to start, throwing a JIT exception. That's when it occurred to me that I had not enabled JIT debugging during the installation of Visual studio. To enable JIT debugging in Visual studio, go to Tools/Options/Debugging/Just-In_Time. Just a thot to let you avoid such pitfalls. That made me wonder if the debugger used is just one, embedded in the machine or each program comes with its own debugger!!!
