Problem in Drawing Lines (AutoShapes)
 

Hi,

When using MS Excel 2000, I encountered a problem during inserting lines
into Excel sheet for a particular file. Every time, after I placed a line on
the sheet I needed to change its color to Automatic; if not, the line would
not be able to see on screen!

Then I tried to close & re-open the file, but the same thing still kept on
happening even until now. I'm wondering why cause it only happened to that
particular file; files created after that are OK! I would like to know why,
could anyone please advise?

Thanking in advanced.
