No problem.  Not much more information here.

On Windows and Linux, we get an occasional error that's similar
in nature - doesn't affect anything, but is kind of annoying.

Hopefully they fixed the burn in problem we saw with 10.4.3. ;-)

Okay, it's in the tracking system so others can search for this
and see the "solution".
