I'm wondering if anyone could give me an answer. Occasionally, when
opening
an Excel worksheet, I am unable to click on any cells or on the toolbars.
I
can't even close out the window. Wherever I move my cursor the cells
become
highlighted, but I am unable to click in any of them. Usually if I close
the
program with "end task" and reopen it the problem is gone. Today it
happened
in one of my worksheets. Closing it out didn't help. I opened another and
had
no problem. Later in the morning the same thing happened in the second
worksheet. I tried opening a new worksheet and the same thing was going on
there. Finally I gave up and rebooted the computer, then everything was
fine. Is there a reason this happens? If so, is there a way to fix the
problem without closing the worksheet? Please email answers to
. Thank you for any info.
