Description

get this message under some circumstances throughout leginon history. see three different forum posts. currently seems to happen with comtypes and when doing GUI type things that interact with the scope or camera.

reason has something to do with multithreaded use of COM. see line in gatan.py related to "COINIT_MULTITHREADED". proabably need similar option with comtypes.

maybe ask Christian about any experience he has had with this.
