Hi John, Thanks I have been looking through the v16 and v17 documentation, I do not see where it says that pasteboard commands do not work with/inside pre-emptive threads.
Also, IP sets, I also do not see any specific reference (one way or the other) regarding IP sets and preemptive threads. I would assume, may be the problem :), that since an IP set can be changed from outside the preemptive thread that it would be a problem, just like an IP variable.
