It is normal for selection mode to be cancelled when you press escape in a dialog, you really don't need to have selection mode open when a dialog is displayed anyway.

I suggest you cancel it before showing the dialog, and start it again under OnDialogResponse.

note: I found that under some circumstances, particularly in dialogs, you might need to delay SelectTextDraw() for a few hundred milliseconds for some reason ( I'm still looking at that )
