Delay in Event handling with multiple loops

[DarkLordOfG]

I have one loop doing event handling through the event handler structure. A second loop is doing image acquisition (Bitflow frame grabber). It seems as though the events do not get handled by the event handler during acquisition. The acquisition is in a seperate thread and I have a 2 processor computer. Any thoughts??

Try running just an event structure VI and a separate image acquistion VI and determine if the events are still not being fired. This will tell you if the issue is stemming from having them in the same VI or just having them running at all together. Also, watch the Block Diagram with Highlight Execution turned on to see if the event structure is ever executing. Let us know what you find out.
