All old documents I pull up from my hard drive and any new
document I start stacks up all letters from a line on top
of one another.  How do I change this?  I have been unable
to find a solution.

For example, if I typed this in word document, the four
lines from the paragraph above would stack every letter on
top of the other.  There would be the A, followed by the
l, then another l, then the o, etc.

Any help would be greatly appreciated.

Thank you!
