Why are Excel 2003 chart arrows and lines invisible with little c.

[Guest]

sWhen dragging arrows and/or lines in graphic charts, they are invisible
except for tiny cirles at the endpoints.

I have used them successfully before but today something is wrong.

Also, dropdown menue of font and palette color swatches contain blank
squares; colors are missing.

I would start by looking to see if High Contrast has been switched on for
this PC. Use Start|Help and type <high contrast> in the search box. Follow
the instructions to turn it on/off.
