A possibly to receive a endless loop if a Tabs messages are processed
in dialog box through IsDialogMessageW .
The reaction of Tabs on WM_GETDLGCODE is return DLGC_WANTARROWS |
WM_KEYDOWN process in IsDialogMessageW in WM_SYSCHAR case. In this case
calls a DIALOG_IsAccelerator function. Inside this function is do-while
loop and send WM_GETDLGCODE message. When this message is send to Tabs
it originates endless loop.
Should help on bug #9781
Prevention endless loop.
