Is MultiTerm API thread safe?

Dear all,

currently, I'm developing a commandline application for importing data into a MultiTerm server database.
Unfortunately, I'm facing issues (System.ArgumentException) in that application. I'm trying to run the ".ProcessImport(MultiTermIX.MtTaskType.mtScript)" in a new thread to be able to stop the import process, if it takes much longer than normal.
The application is developed in Visual Basic.
My question therefore is, if the API from MultiTerm is thread safe and if it is possible to outsource the import process to a new, independent process/thread.

If you have any further questions or any hints, please don't hesitate to let me know.

Thank you very much in advance for your soon reply.
Best regards and have an easy day
Nils
