Dysfunction in the IT of civil engineering (and similar) professions is fairly common. I remember this exact phenomenon too - of Irfanview's default UI controls not suiting what the staff were used to. And the staff didn't need The Most Powerful Tool Under The Sun, they just wanted to view and zoom and browse, and a few other tools, using the keypresses and mouse movements they were used to from previous software.

And Irfanview could do those things in it's sleep with both hands tied, with a few simple config changes. But the dysfunction - often rooted in the minimal, grudging acknowledgement given to IT by (non-IT) old professions - led to a lot of half-assed setups where staff butted their heads against obstacles that were often a mere few clicks away from improvement, if only they'd known to put their attention there. But of course, they were too busy being civil engineers.

And if I may shoehorn another point in here : it's not as though AutoCAD and other such industry software comes with ready default settings. If you used those straight out of the box with no customisation for your own situation, you'd be in deep trouble.
