My daughter managed to change both her foreground and backround colors to black. I can't even tell where a window is, much less select options, so I can't change the settings. Is there an easy recovery for this or do I have do delete her account and start a new one? I tried (for the first time) to start up in safe mode, but my Dell ignores the F8 key on start-up. Is there a better way? Thanks in advance!
