>W2.0 was a nightmare. I already had lots of experience with graphical shells - used GEM for DOS (on an Amstrad XT - remember those?) and Atari for a number of years, already had good reflexes with the mouse, but no, W2.0 was not even close. It was the first piece of software where I couldn't find a way to exit. It kept me clicking in circles, without any way to remember how I got to the current screen, nor a way to get back but by random clicking. I was totally lost within minutes.

I had written a program depending on lots (back then) memory on Atari ST, which was then used throughout europe and on PC's when extended memory came along. First port was to Prospero Pascal, which ran on 6800 and Intel and could reuse in Prospero Fortran some of the code I had written modelling on a DEC university backend, then moved all over to Modula II when I had to run with minimal memory and had to introduce multitasking in DOS program... Wonderful times where you ran into terra incognita every other week.
