I once beta tested a funky little program for authoring Windows Help. It was written by a really nice guy who had absolutely no clue that there were standards for Windows user interface design, let alone how to follow them. Just to give you an idea, if you tried to add a graphic, it had to be a .gif. If you tried to add the wrong file type, the program would go into an endless loop, telling you you'd selected the wrong file type but providing no way to fix the problem. "Sorry, Dave, I can't do that..."
That's when I discovered that the user interface had no escape. No Exit button. No little X in the upper right corner. No close option on the menu in the upper left corner. Welcome to the Hotel California of software applications - you can give up any time you like, but you can never leave.
I started imagining zombies taking over my computer. In exasperation, I pressed CTRL+ALT+DEL (which, back in the day, would restart the whole system - not merely bring up the option of starting Task Manager). "Crash now and die, dammit!" I yelled, jamming my fingers into the keys like a crazed woman. And from that moment on, CTRL+ALT+DEL had a new nickname.
Microsoft, take note. When I choose "End Task," I mean it. Don't tease me, then ignore me or say, "I'm sorry, Dave, I can't do that." I love Vista and I think Internet Explorer 7 rocks, but why is it every time I come back to the PC, my programs (the same ones that were humming along beautifully not an hour ago, like Internet Explorer 7) have decided to take a dirt nap and refuse to respond? Or, if they respond at all, do so grudgingly and sluggishly and half-heartedly, until I'm forced to invoke the "Crash now and die, dammit" option and recycle the pixels?
