NI-serial 1.5 on dual cpu system

In NI-serial version 1.7 and higher it mentions its multiprocessor and hyperthreading safe. In version 1.5 this isn't mentioned.
What can i expect if i use version 1.5 on a dual cpu system running windows2000 where hyperthreading is enabled?

The problem we see at our system, partly answering the previous question, is as follows.
In our current system we use NI -serial 1.5 with a PXI-8420/8 card with windows2000 and sometimes the application simply freezes and we have to restart the pc,
in order to regain control.

Should we upgrade to a more recent version with multiple cpu support?
and which version should be used than?

Anyone has any suggestions for me?

thanks in advance

I would expect behaviors similar to what you are seeing when running a NI-Serial 1.5 on a multiprocessor system. The best solution would be to upgrade to the latest NI-Serial version which is currently NI-Serial 1.8.
