ARM-USB-OCD not stable on Windows 7

[Richard]

Hello

My configuration is ARM-USB-OCD <==> LPC2148.
On Windows XP it works fine. But on Windows 7 it works only about every 5th time.

Has anyone a solution?
Below you find the results of two runs and the content of "lpc2148_flash.cfg"


Thanks for help.

Richard
