Hello again,
I've gone through all demo, test and tutorial, the ones which failed are:
Forms, Tutorial_08 and 09 (that use forms)
Test env: last Gnoga on SF, GNAT GPL 2015 on MacOS 10.11.4 with Safari.
Then I use "gdb bin/forms" with "catch expression" and "run" then click on
button "send to demo via post":

It is just fist elements of test.
My first guess is that occurrences of Gnoga internal exception are masked and
may lead to connection error.
Thus it is not so easy to find the root cause.
Same test on Linux or Windows would be welcome.
Is it possible for you to run your program with gdb catch expression then
backtrack display?
