Larry, you'd better check your books again – It is the fseek(FP,x,0);
instruction which has the bug that Rob Peck confirmed that was a real bug.
Larry, re DOS vs Intuition, it's all in the same machine, and who knows why
windows can be dragged off the screen, but the strange thing is that it
only happens if you drag the window with a swift 45 degree pull to the
bottom right hand corner, and only happens with custom windows — If you
use a NEWCLI onto a Custom screen (for 8 colors, etc) it doesn't screw up –
To quote Rob Peck again 'There are differences between workbench windows
and custom windows.'
Maybe it's just that we are pushing the machine to the limits (again)
