Can you set a flag in your code-behind, and branch your code so that second or subsequent clicks/calls don't do anything?

A SWAG: maybe the browser is queueing mouse clicks or ENTER key hits on that button. Still, that might not be the cause of the problem - if your code behind disables the button, once posted back the button will be disabled and any mouse/keyboard action applied to it should do nothing anyways.
