It's all about the Software

In SDRPlay RSP1::SDR Console v3.0.26

In the Rec/Playback tab
clicking on the "Record" button in the Data:Record section brings up a "Start Recording" window.
It appears to be extending beyond the bottom of the screen. Screen shot attached.
Its "start" button can not be seen or clicked.

Windows 10, automatically updated
Dell laptop
The same thing happens on the laptop screen and on side screens.

Version 3.0.24 had the same problem on this laptop. Used version 3.0.24 to remove all the registry entries, then removed it, and installed version 3.0.26. The problem persists.

You didn't attach your screenshot.

The "Start Recording" window extends below the screen, so the "Start" button is unreachable.

Just what screen resolution are you using?

Edited to add: Changing my resolution to 1024x768 and disabling scaling & I can't recreate what you are seeing.
