Haha, yes I too have a very soft spot for those early Microsoft GUIs. Though I played Minesweeper more on Win 95 I definitely hit it hard on 3.1 and 3.11. So the 'X' button on your dialogue box did feel like a luxury, I agree ;) I miss those happy days of organising stuff in Program Manager, meticulously arranging icons then having either Windows go nuts or a cruel friend / sibling hitting auto arrange...
I remember the excitement of unpacking my first ball mouse - my dad's CPC1640 in 1988... He used to do DBase III and FoxPro stuff (my first job in 2001 was somehow in FoxPro too..! Visual FP at least)
