File taking long time to move w/in sheet and process

[YellowLabProject]

My file is only about 100 records. I have some formulas and conditional formatting in the file.
When I use either the vertical or horizontal scroll bar, it takes an unoridinarily long time to move on the screen. What used to be instantaneous now takes up to 10 seconds.
I have deleted all the conditional formatting, deleted the macro buttons, and still experience this painful delay.

In a new file w/ no records, just to run as a test, the new file runs fine. So I have to make the guess, that, it is not in the Excel setup-- tools or options.

How do I find the problem?

thanks,

YLP

YLP,
Isn't that a Golden Retriever in your avatar? Cool looking dog. Anyway, you've tried closing and re-opening and re-booting?

Oh yeah- a Yellow Lab to be exact...

Yes, this file is testing out on several systems w/ this behavior. It is definitely in the file, just wondering where...

thanks,
