NULL parent Dialog Clicking Up/Down In Messages
Problem: When using the form viewer to look at messages on an Outlook box, clicking the up/down button on the message to move to the next/previous message pops a dialog:
"Form Viewer created with a NULL parent!"
This is fallout from my work to ensure windows were properly parented. This dialog was left in to identify missed cases. Problem was OpenMessageNonModal had no way to pass in an HWND for a parent, so we always had to guess. Opening a message and hitting next
message got us into a situation where we could not guess.
Fix: Add an HWND parameter to OpenMessageNonModal and use it.
