Why does my excel freeze up

[Jack-P-Winner]

I have rather Hugh excel files. Each book is 1300 kbs. When I open them up and use the bar on the right to page down it goes good but if I try to hurry the scroll up the page frees on me and I have to wait what seems forever which can be a few minutes or longer. (I have to close and re open). Why does it do this and what can I do to stop this from happening

Hi Jack-P-Winner,

If there is any event change (like selection change) macro in your workbook, that could cause this to happen. Just check it.

Regards,

hm, selection change. I have lots of things that change so I do not understand

I installed the 64bit and all my problems went away. Now for the protection issue
