[SOLVED] Arduino uno: avrdude: ser_recv(): programmer is not responding

Hello,

after trying for one whole day to connect to an arduino, i managed to connect to an arduino uno over mkII at the ISP Header. There i installed the boot loader successfully. But if i try to upload a sketch threw the arduino ide, it always complains:

avrdude done. Thank you.

Does someone know how i can bypass this nasty error?

regards

I figured it out: when i upload it from a terminal with avrdude, it is working flawless. This seems to be a problem within the arduino ide, which i experienced very often.
