Hello,
i tried that shift-thing, didn't show anything.
Then i enabled the "verbose output" while uploading, and that's the result:
C:\+ARDUINO\ArduinoIDE-1.0.1\hardware/tools/avr/bin/avrdude -CC:\+ARDUINO\ArduinoIDE-1.0.1\hardware/tools/avr/etc/avrdude.conf -v -v -v -v -pattiny84 -cstk500v1 -P\\.\COM4 -b19200 -e -Uefuse:w:0xff:m -Uhfuse:w:0xdf:m -Ulfuse:w:0x62:m

avrdude done. Thank you.
The Attiny is probably not the problem, i tried both Attiny85 and Attiny84.
Is it possible that the Leonardo doesn't work for this stuff because of it's internal USB controller?
