"Advise marshal failed"

Any new info on this error? I'm getting it pretty regularly now. I have a wireles IR PC keyboard that seems to trigger the problem sometimes but not every time. Like others who've experienced this, I have yet to pin down an exact repro scenario.

Another symptom I'm seeing is that Slinkx.Send sometimes fails for no apparent reason. That is, the result returned is non-zero and the IR command does not get issued, but Slinkx.LastError is empty. Once it gets into this mode, the only solution seems to be to quit my app, shut down SlinkeServ, and reload. Not sure if this is related to the first problem or not.
