Thanks for testing and letting me know, Octavian.
Unfortunately, I can't replicate the problem so far. I uninstalled the
Nemerle distribution, and made sure the directory tree was deleted in case
there were other dependencies upon which n_fruit.exe was relying besides
the .NET Framework. The program still runs fine for me. I suppose it's
possible that some other file did not get uninstalled, but I also tried
running from a command prompt after clearing the PATH environmental
variable to prevent Windows from looking for DLLs in other directories.
I think the focus issues are related to JAWS 6 and the .NET Framework.
I notice some, though not as much, with JAWS 6.2. JAWS 9 beta is not
showing these problems for me.
