MSGBOX not working properly

[bobspen@…]

just started using a 64 bit Vista Laptop. I upgraded Autoit to latest version. I am running some scripts that I developed under Windows XP and getting strange behavior of the MSGBOX instruction. I have several MSGBOX thru out script, all set to be an "always on top" window. One behave properly and the next does NOT stay on top most of the time. The two lines are:

Works correctly: MsgBox(262144, "Decryt Password?", "OK to Decrypt?")
Works incorrectly: MsgBox (262144, $B, "ID/Name= " & $C & Chr(13) & Chr(13) & "Password= " & $A )

Any clue as to what might be going on???
Thanks for any help,
Bob
