Many thanks to all of you. But, hey, I'm not running Windows 95 but Windows XP Home SP2. If the log shows Windows 95 then there's obviously a wrong setting somewhere. I cannot see where there's any place to reset this in ImgBurn. I have 27GB free diskspace, 512MB DDR RAM 334MHz, 3.06 GHz Mobile Intel Pentium 4. The fault is obviously with me, not the computer, so be kind to it! Again, instruction would be gratefully received.
