I tried opening several documents, changing each one into Full
Screen mode, then closing one of them. While the Mac menu bar and
dock appear briefly, the next document did appear in Full Screen
mode as expected, and I didn’t end up viewing the Desktop, or
in the Finder. Can you let me know what version of iA Writer and
Mac OS X you have, and if there’s anything else I need to do
to reproduce the effect please? Or if I’ve misunderstood,
please let me know.
When you say you end up on the desktop, is iA Writer still the
active application (iA Writer beside the Apple logo in the menu
bar), or are you ending up in the Finder? In the former case the
only thing I can think of is the documents might be being minimised
somehow, the same thing that happens when you click on the center
minus button in the top left of a Finder window. If you set up
Exposé to show Application Windows when activated, then
activate it after ending up seeing the desktop when you expect
another window to become visible, are the documents presented as
large previews or small thumbnails at the bottom?
If you have any Finder modifications such as things that change
the behaviour of Finder windows, it’s possible there’s
a conflict there. Apart from that all I can suggest is to try
deleting the app and reinstalling it from the App Store.
I’ll close this discussion for now, but please feel free
to open it if you want to add anything further.
