Can't scroll in log files ... Bug?

OK when i have my log files open, I can scroll up and down no problem using my mouse wheel. I can highlight and copy no problem. BUT

If I try to use the little handles either up and down or left and right, it locks up. I have to close out, then I have to click a button to reload to even get anything back.

This is repeatable over and over. I am on a 27 inch iMac running the latest version Sonoma.
