AskYesNo box always shows up behind main installer

[Sam_Hosig]

So I have the following code and anytime it is called it appears behind everything else. Does anybody have any idea of how I can make sure this prompt shows up at the front every time?

sPromptA = "Question that is asked to user";

MODE = NORMALMODE;

if (NO = AskYesNo(sPromptA, NO)) then
MODE = SILENTMODE;

I have the same problem. What can I do to bring this dialog to the front.
