In the past, the same program (written in lazarus ) running in the same hardware pi 2 under the older raspbian version has NO PROBLEM.

But the SD Card was corrupted so I installed the latest raspbian OS jessie on the same Pi 2 on a new SD Card. I reinstalled everything (e.g. mysql etc) and my program and it runs fine EXCEPT that pressing a key once will gives multiple letters. BUT this problem only occurs with my program. All other programs e.g. web browser and file managers , text editor DO not have this problem.

I already set the Menu-> Preferences->Keyboard and Mouse->Keyboard-> Character Repeat->Repeat Delay to the maximum (1000 long)
but still does not help.

I cannot ask raspbian forum as they rarely write free pascal programs.

Can anyone think of what special things that lazarus GUI program uses (e.g. QT, gtk ) that might not work with the new raspbian jessie?

Note: I have tried installing FPC 3.0 and latest lazarus on the pi 2 raspbian jessie and recompile the program but it has the same program.
