I'm using QV11. I've also tried my example in QV10 (SR3). In QV10 it's indeed not possible to add a reload action. It's not available. The interesting thing is however that the reload action I added using QV11 can still be used if the document is opened in QV10.
The triggers I added can be found on the Triggers tab of the document properties screen instead of on the sheet properties screen.
