The scrollbar on one of 6 worksheets in an Excel program
approximately 6MB in size mysteriously stopped working. I
can no longer scroll down the page and when I try to do so
the scroll bar moves but the page is idel.

I developed the file on my hard drive and then transferred
to a network through Citrix. I started having the problem
on the network so I took it off but it is still happening
now. Again, it only happens on the one worksheet but the
other five are fine.

Any ideas?
