 Hi Matt,
Not really questions for this list but here goes.

No. While script is executing nothing much else happens. The settimeout allows the window to update the status bar. Try a forever loop and see what doesn't happen.

Not that I know of.

No. simple <script elements are just output to the result tree. <msxsl:script elements are executed during transformation but use only the basic language. alert is a method of the window object so isn't available.
