php-switch not switching properly

[StephenGlynn]

When I use php-switch.bat to change from php 5.0.2 to php 4 I get a confirmation message that everything's been changed properly.

However, when I restart xampp, I get a series of warnings that various extensions aren't installed and then, when I run phpinfo() I find I'm still apparently running php 5, only without the extensions I've just been warned about.

What should I do?
