Re: The strangest call I ever had
This reminded me of being in on-site in 1990 the first week a new dealing room with our software went live. One user asked for help, both screens of his OS/2 system were nearly entirely black. Turned out he'd gone to the control panel and changed every color to black. Scroll bars, foreground, background, title bar, the lot.
Used another system as a reference to keystroke my way back to default colors.
