On Vista - a message box hides behind "Please wait while windows cofigures.."

[itsvnay]

I use Basic MSI for our product, and during uninstallation event -- I call a custom action to prompt a user for his input.
if (IDYES == MessageBox(@AskSaveUserFiles, MB_YESNO)) then..

Note: I have tried calling MessageBox with "MB_SETFOREGROUND", "MB_SYSTEMMODAL" argument as well, but they didn't help!!!

This works fine with XP OS, however noticed in Vista or Win 7 OS, this message box always hides behing standard installshield wizard "Please wait while Windows configures [ProductName]"

Q#1) How can I bring my message box infront of InstallShield wizard dialog?
Q#2) What's the control/event/InstallationSequence that calls InstallShield wizard dialog mentioned above?

Thanks,
Vinay
