If errorCode contains a percent sign in some way, you'll get a crash or other odd behaviour when the sheet interprets it as a format and tries to interpret whatever is on the stack after the parameters as arguments.

Thanks, it did not dawn on me that since I wanted to pass a string, I could just pass it and use as the parameters my own parameter...

In this case should be benign as the errorCode is always a 4 digit hex number.

I am re-architecting the place in the app where this stuff happens (registration etc) so maybe whatever the problem is will go away.  It got too convoluted as I added new layers to the app startup.
