The installation settings page, where there's a list of settings with 
hyperlinks and headings and things, is quite confusing. Partly because it 
doesn't look very nice, so one instinctively thinks it must be complicated. 
And also because when an option is selected, you have a back button and an 
abort button - which at the start both do the same thing. But I wasn't sure 
whether the abort button would abort everything or not. And it's not obvious 
that clicking next will take you back, eventually, to the installation 
settings page, so I was hesitant to click on it because there were still more 
settings I wanted to change, and I didn't want to click next too many times 
and leave that page.
