Thank you Roi for your interest.

Unfortunately your remedy didn't work. And let me add something to my original posting. In problem 2, when LOADING form begin to show few seconds of interval need for animation to play. But the next line of code '=requery()' halts the entire screen (guess for connecting to Oracle) and the LOADING form also is influnced. I wish the LOADING form shouldn't be interupted and played indepandantly.

Waiting for any ideas.
