Don't use crit sections with anything GUI related. It's all serialized via message queues. If something doesn't work when using SendMessage() then you either doing something wrong, or it's a bug in Wine. In first case - check if it works on Windows. And if it does - file bug in bugzilla. Also note that Wine's implementation of RichEdit is still pretty weak and does have significant issues.
