Programming just once

Development Tools IDE 1.x
1

First I want to say that I posted this topic (http://arduino.cc/forum/index.php/topic,119955.0.html) and I made some progress but I have new issues now.

I am able to burn the bootloader using the arduino as isp. Then I use a FTDI board to program it. And it works, the problem is that when I want to program it again (or upload a new scketch) it gives me an avrdude get_sync error. But if I burn the bootloader again, it allows me to program it again just once. Anybody know what it could be?

It is all connected together (and after that I burn the bootloader and then the uploading works just once), so it should not be a connection issue, but so far I have no clue what it could be. I can work with the board but I want to avoid the bootloader burning every time.
Thanks!

My guess, and just a guess, is that the target board/circuit you are mounting the chip in after burning the bootloader is not handling the Arduino auto-reset pulse. Could you give more details about your target board and or the FTDI module and how you are wiring them up?
