Blank screens, why?

[Baantjer]

I am presently using Process hacker V. 3.0.4953 And both of the screens which are meant to show information on the disk and firewall are completely blank. The other screens show the information with no issues.
I can see only view the column headers.
Why is this and how do I get them to display information?

WIndows 7 doesn't have much support for these features. You'll need Windows 8 or above.

thank you for the explanation.

The Disk tab should work fine on Windows 7 but only one application can capture Disk events.
