Finally I found some time starting to explore the new iFly 737NG for FSX together with FS2Crew Voice and both products are great and the combination is even better!!I have one problem though I've seen on all flights I've done so far, when I get to step 4 in the Before Taxi section on page 46 in the manual and call "Before Taxi Checklist" the FO won't respond. I've checked I'm in the right mode and that the green bar shows what I say is understood correctly. The only way I found to get around this problem is to manually advance to the next mode using the arrow and then go back and call for the "Before Taxi Checklist" a second time and then it works just fine.Any idea what could be causing this?TIA,

Did you get through the "Flaps TO Set Window" and did you tell the ground crew "You are cleared to disconnect and go to hand signals" I had to do it a few times till I got it right "flaps 5" then do the check list.

Thanks for your input, I'll make sure to perform the steps in the exact order you suggests and report back.

Yes Right after push back give the Ground Crew the orders then FlapsTO window shows up then state: Flaps 5 and do your flight control check and check list items and Call For Befor Taxi Check List.
