Camping to char select and picking another char crashes client

[Tynker]

This has been happening since I downloaded and installed the 4.6.8b version. When I camp to char select and select another char, I get the message "Entering World" and will crash the client. I have saved the crash file if that will help. I have 2 systems with the new version and 1 without it, the old version doesnt have this issue, both with it do. Ideas?
