I tried to reproduce your problem, but I couldn't. I created master page with custom control on it, then created a page ( named "page" ), based on this master page. I made this page to not be homepage. Then I created 3 parent pages for this page in hierarchy. When I loaded the "page" named page, the control's Page_Load was called only 1 time.
Can you give me some specific instructions how to reproduce this, or send me your DB, config files and any custom data that I need.
