The scroll starts at the bottom of the page in one file. It starts at the
top, as it should, for all other files. How do I change the scroll to start
at the top on the one file that starts at the bottom?
Scroll bars appear wherever they're needed. If the file is too long to fit
on a single screen, a vertical scroll bar appears; if too wide, a
horizontal scroll bar appears. If file is too wide and too long, both
horizontal and vertical scroll bars will be present.
Cannot tell you how to change the file in question since you did not
mention what kind it is. An example: if text is involved, change the page
margins (or turn on word wrap) so that each line of text is narrow enough
to fit the width of the window normally used to view it.
NOTE: Careful with adjusting margins. If you resize the window displaying
the text, the scroll bars will reappear and if you decide to print the
document the results may not be what you expected.
