Library material message locks up Rhino Wip every time

This has been happening in the last and current wip builds. It’s a real bummer because you will lose lots of work if you run into this.

If I am not connected to the internet and I drop a texture from the library tab onto a model Rhino pops up a message but if I click ok nothing happens. Rhino is hopelessly locked and I have to shut her down using the task manager, The worse thing is you lose all your work so be wary of this it got me twice already. Rhino should not lock up after this message. Clicking ok should work but for me Rhino locks up and has to be shut down via task manager losing lots o time and you know.
