LVOOP %27owning library blocked execution....%27

[DavidMaidman]

Hi All

I am working on a project using LabVIEW 8.5.1 (specfied by the customer not me!) and am having trouble with some LabVIEW classesI have created. I have created three classes - a parent class is a 'generic DAQ class', and card specific classes that inherit from the generic class overridding all methods. However I get an error that I can not get rid of... 'the owining library has blocked execution'. This is for all VIs and the class data types. I have opened the library using LabVIEW 2012 and 2013 and I do not get the same problem in either of those. Any thoughts?

I have found the issue. One of the overridng methods of one of the child clases did not have the 'dynamic dispatch' output terminal wired correctly - newer versions of LabVIEW must handle this better.
