Sketch lost when serial port closed & open

Having a weird problem can't seem to crack.

I've got Firmata v2 up and running on LINUX UBUNTU using a Flash app with AS3Glue, everything works great.

I then ported over to Windows XP (SP2) using serproxy as the serial server and everything works fine except that every time the serial port opens and closes (reboot or just unplugging the Arduino), my sketch (Firmata v2) is lost.

I've tried both firmata 1 and 2 with the same results. Given everything works fine on LINUX including re-booting without having to re-download firmata, I would think it would be some XP setup thing? I also tried upgrading to the latest and great FTDI drivers, still no luck though.

I have an Arduino NG, Diecimila, and Duemilanove. Problem only happens on the Diecimila and Duemilanove so I guess its related to the bootloader process.

my circuit is on the last page of this PDF http://www.diymagicmirror.com/diy_magic_mirror_manual.pdf

Any ideas would be appreciated, thanks.

Could it be the Arduino auto-reset feature that uses the serial DTR control signal to reset the AVR chip? Removing the cap from RTS to the reset line should prove that out. However if you leave it removed you will have to manually reset the Arduino when loading a new sketch to it.

I suspect that's it. I just didn't know how to fix. This is a physical cap on the board that I un-solder and remove? A little more detail there including where it is would be great.

Thanks for the assistance!!!

Well I own a clone type serial Arduino, it has the auto-reset cap also but would probably be a different component number then yours. Perhaps someone else can provide the details you need.
