The % Fragmentation in Analysis results changes to match the current state during defrag. Surely the point is it shows the analysis results from before the defrag?
The Fragmented Files and Total Fragments remain intact.

I think the idea is that it will show you fragmented files that remain post-defrag.
I think this is a bug.

Analysis results should not change when defragging.
I think it's an intended improvement, otherwise Piri would have addressed it by now.
Maybe a dev could chime in and let us know the intended function of this?
If it's a feature rather than a bug it could be toggled on/off via a configuration setting. Otherwise, I do not understand its use.
As I say, it keeps the "Fragmented Files" and "Total Fragments" values so the percentage figure is wrong if it's supposed to be based on these.
It has happened to my machine (Windows 7) recently - fragmentation percentage remains unchanged after the program stops running. When I run the program again, it works like snail, scanning each and every file on my HDD......

You appear to have a good amount of free space.
Have you tried
Update to 2.09, then go to settings/options/advanced & checkmark the following:
- Stop VSS when defragging
- Use custom fragmentation settings & check both those options
- Uncheck cache analysis of multiple drives
- Save to .ini
Then, click ok.
I notice you are running in Basic skin mode. Do you have all your drivers installed for your Sata drives/Display/Audio, etc.? Or does your computer simply not support Aero or have it disabled for some reason?
Am not sure if you have it fixed yet, but you may also be able to run it in debug mode & post a logfile to assist.
Thanks!
