Fix wxMSW rendering artifacts with modal dialogs.

Browse Source 
When a modal dialog showed another modal dialog, parts of the parent
window weren't refreshed correctly. This demonstrated itself as
rendering artifacts when moving the child dialog to another position:
parts of the dialog were shown as disabled, parts as enabled.

Fixed by explicitly refreshing the window.
