Does wine send window messages without waiting apps to reenter userdll?

[Sebastian Lackner]

Thanks for providing the testcase. It indeed looks like a wine bug. Would you
mind to open a bug report on bugs.winehq.org with your testcase and explanation?
Feel free to add me as CC.

The following quick & dirty hack fixes the issue (but will very likely break
other stuff): http://ix.io/kx0

Does it also help for your app?

Regards,
Sebastian
