Rob,

Clicking on a link invokes "activateslide".  The last line of this function makes a delayed call to "slideit", but so does "slideit".  I.e. slideit is calling itself.

Repeatedly invoking "activateslide" generates more timeouts which will all lead to more and more frequent executions of "slideit".

I'm not 100% sure what your desired behaviour is, but suspect you may want to either:
a/ Store the integer returned from setTimeout() so you can pass it to clearTimeout() whenever the user invokes "activateslide".
b/ Use a simplified design based on setInterval() and clearInterval().
