On behalf on national Instruments I apologise for this troublesome bug's inclusion in LabVIEW 8.6, and we thank you for bringing it to our attention.
The corrective action request (CAR) my colleague made on your behalf has been accepted by R&D. This quarter's Dev Suite was what we call a "minor software release" - 8.6.1 being a revision of the 8.6's architecture. The issue has been forecast to be fixed in the next major LabVIEW release. Unfortunately, as we have yet to set official release dates, I am unable to speculate on when this will be available to you.
I apologise I can not help you further. However, I assure you that the R&D team in the States are working on resolving the issue.
Best wishes and kind regards,
