[OSK] Handle the warning dialog box in its own thread

Browse source 
The dialog box at the startup of On-Screen Keyboard is displayed alongside with main window. While the Microsoft's OSK in XP is written in MFC and OSK is actually a mere window whereas our OSK is a dialog, the main dialog procedure call is superseded until the user does something with the warning dialog box on startup.

Just create a thread for it and handle the dialog box on startup in its own thread.
