Migration to LabVIEW 2012 from 2010 causing problems

[Strokes]

Hi,

I'm porting some applications from LabVIEW 2010 to LabVIEW 2012 and am seeing some weird behaviour.

Have NI changed the operation of the VI:Execution Reentrancy modes?

The applications function as expected in LabVIEW 2010 when using shared clone reentrant execution, however in LabVIEW 2012, this mode is causing problems whereby data neither enters or leaves VIs with execution mode set to Shared clone reentrant execution.

I can resolve the issue by changing the VI execution mode to preallocated clone reentrant execution but I'm not sure why this didn't cause an issue in LabVIEW 2010

Any ideas?

Hi Strokes,

Is there any chance you could post your code, or a basic representation of it, so I can try to replicate this?

Kind Regards,
