Mac Rhino Crashes with putting dimensions

Using 5.1 5B161

Using in Japanese mode.
Below is screencap just when spinning wheel turned up.
Is this known issue? Is this only for JP?

The data itself is really really simple stuff.
Anything I can do to fix?

not running much, Acrobat reader, and keynote in the background.

Hi Toshiaki-

Unfortunately, I cannot reproduce this crash with the information you have provided. Is this only happening in the 5.1, or does it also crash in the latest RhinoWIP? We’d like to reproduce the crash if we can so that we can investigate. Please check out the How to write a great bug report in the Reporting Problems thread.

Thanks,
-Dan

I’ll see if I can make a file to reproduce it.
