Tuning via click tuning behaves strangely in MW and below. The attached video illustrates this. SDRC 3.0.25 on an Elad FDM-S2.

What's the problem? I can't see one.

The problem is that the tuning doesn't track where I click. Watch the green tuning indicator when I click. It appears in a place other than where I click.
For example, when I enter "170" on the keyboard to tune to 170 kHz, I see AM broadcast stations offset from where they should be. The first one, at 840 kHz on the display, is actually at 560 kHz. Note that when I click on the signal at 840 kHz, the green band that indicates where I'm tuned actually appears at 560 kHz.

Hi please show this step-size window.

None of the screen capture tools I have will let me capture that, including the screenshot tool built into SDRC (the "Step" dropdown closes as soon as I try to take a screenshot), but mine looks identical to yours--"Snap" and "1 kHz" are checked.
It appears this issue happens whenever the span is set to a higher value than the tuned frequency. For example, if the span is set to +/- 700 kHz and I use keyboard entry to tune to 170 kHz.

1. open that window (pane) and push the PRTSCR-Sys key on your keyboard
2. open Windows Paint
3. press CTRL + V keys
4. use Select and Cut to select only the SDRC window containing the pane (in case you have 2 or more sreens)
5. save pic as "xxxx.png"
6. attach the pic here by using the button "Full Editor & Preview"
PS Don't make Simon angry, always send the full SDRC screen (don't crop or cut parts and leave it high res)
