About two months ago the below thread started and it seemed to fizzle out.

I am experiencing the same problem and wanted to know if I missed something or if no further exploration occurred. A brief search of the bug tracking system did not seem to produce any open bug reports for this issue, but I figured I would check here first.
I will wait to hear any feedback as to the proper venue for any additional information I have observed. Thanks for your time and any help.
