I am aware of the problem that the Oracle Forms API can be a bit "fragile" when processing many Forms at once. Whenever i call out of my side of the code into an Oracle API function then i have no chance of managing exceptions or hang-ups. The only solution to this problem would be to rewrite my tool to use a multi-process architecture (like Google Chrome browser has done) - so that i can kill a hanging process and recover without affecting the main-application. But then everytime i would want to extract Forms properties and objects i would need to send that data between different processes and that would make search (and compare) very much slower than it already is ... so i am a bit stuck with how it is  ;-/
