Hello,
I am running a workbook that is shared by a few users. Occasionally, we
lose the side (up & down) scrolling function and we have to close the
workbook and reopen it and then everything is fine. I think this may be link
to using filters, but I can not narrow down the exact cause.

Has anyone had this happen to them? What is the cause? How do I fix it?

Any help or ideas would be great. Thanks,
