Tested again without inserting a USB-Stick
Yes, everything hangs up when hitting win+E, ImgBurn seems to recover sometimes but is not able to proceed correctly, I attached the log of my last try.
To reproduce: Write files to disk -> after writing the lead-in hitting win+E
-> explorer does not fully show up, vista declares explorer does not respond any more, ImgBurn does not write any more, rate drops to 0
... [letting time pass does not seem to change anything]...
-> launching task manager (wdm.exe seems 2nd biggest process (next to ImgBurn) in amount of memory and cpu usage -> kill wdm.exe)
-> klicking on explorer again -> vista tries to restart explorer ... layout/explorer completely broken
-> ImgBurn somehow pronounces many retries in writing
-> closing ImgBurn lead to some error message ...
I'm using the default installation (no config change to default), i.e. I/O is SPTI
Tried to check other I/O-interfaces, but they don't seem to be shiped by default installation ...
