First thanks for that nice piece of software. I had to check the PHP code of someone, and thanks to this portable WAMP, it was really easy and fast to do. A tiny annoyance I ran into is that I have MySQL installed on my developer PC, and I first have to stop it before running Start_as_program.exe (the PHP code I had to check was simple and didn't use any DB). It could be useful to only display a message but still allow the user to continue. Then the "Start MySQL" button would be disabled. Thanks.
