Agreed JK.

I always remove the selection for automatic error handling.

I didn't know that.

And you can keep not knowing it, because it's not true. AEH dialogs do NOT appear in built executables. If you have an unwired error terminal which has an error, the error information is simply lost. I suppose it's possible that this might happen if you enable debugging in the executable, but you generally shouldn't have EXEs running in debugging mode.

tst, is it not that an unwired error terminal (w/o connected to an error cluster indicator) must be connected simply to a frame (for the error dialog not to pop up) so as to lose the error? Else, it will popup even in built EXEs, I think ...

To make sure, I even checked - AEH dialogs do NOT appear in EXEs, even if you have debugging enabled (which some may even consider a bug - you could argue that if debugging is enabled they should appear).

In any case, AEH is not a proper replacement for error handling, but it has its advantages. We've already discussed this in the past (here, for instance).

• Controls/Functions Palettes > Loading > Load palettes during launch - Assuming you haven't been hiding under a rock for the past year, you should already know that this is the option you must select if you want Quick Drop to be immediately usable after launching LabVIEW.

I'm rather fond of the "Slow Drop," myself, so I like to leave that box unchecked. 

(I'm kidding.)
