Form focusing and popping up when i don't want it to

All right, i have a form with two webbrowser controls that work with an outwar.com thugbuilder. This page automatically refreshes one of the browsers, and loads another URL in the other browser. The problem im having here is that i have the form set to stay in the system tray when it is minimized, but every time it refreshes the window changes itself from minimized to normal, and pops up (and because i have it set to be in the system tray only when the form is normal it takes it out of the systray). Is there anyway i can prevent this from happening?? cuz it annoys the hell out of me.
