--- Comment #1 from Henri Verbeet hverbeet@gmail.com 2011-09-15 09:17:41 CDT --- This one may be hard to fix. IIRC the last time I looked at Nox it was modifying surfaces without locking them first. This works more or less by chance with the gdi renderer, but it will probably be hard to make it work in a reliable way with anything else.
