Unfortunately, I have the same problem, and I don't even have to click on anything in the preview window:
- in an edit window I click on an element
- when the preview window shows the location of the definition, I move the mouse into the preview window (I don't click!) and roll the mouse wheel down (towards my hand), and the definition location is shown in the edit window, opning the file if necessary.
- If I roll again, the definition that happens to be in focus in the preview window is then shown in the edit window.
- If the preview window doesn't show anything, SE opens a new file 'Untitled<nnnn>'.
I observed this with SE 24.0.2 Hotfix 21, I just downloaded 25.0.0, situation unchanged.
I use Win10, and a Logitech Mouse MX Master, my language is C/C++, and my emulation is set to "SlickEdit (text mode edition)".
Different, and maybe unrelated:
If I use a split edit window, make it show two different files, and hover the mouse over the inactive window and use the scroll wheel, both windows are suddently showing the file from the inactive window.
Not just weird, but very tedious!
I'll see if I can find an update for the logitech app that I think I am using, or maybe deinstall it. I also tried several W10 mouse settings, but no luck.

Edit: I updated "Logitech Options", no change; I unistalled "Logitech Options", no change.
