[VS 25.0.1.0, Win64 10, Brief, C] I normally run with a defs window to the left of my main edit windows. I've noticed a couple of oddities.
The first is that sometimes when I double click on an entry in defs I jump to somewhere else. This only happens occasionally, but it happens just often enough that I don't think it is finger trouble. Normally when it happens I'm in a large buffer that I've just swapped to, but I've completely failed to generate a reliable test case so this report is mostly so that if you ever see it happening you know it is probably real rather than you imagination.
The second is trivial but reliable. Double click on an entry in the defs, that takes the edit window to the line with a flashing cursor, single click on another entry, cursor turns into a grey block, click into the edit window you get a flashing cursor at the previously selected function start but the highlit line in defs doesn't change. Move the cursor and the defs highlight moves to the correct spot. I think the defs highlight should move as soon as focus moves back to the edit window.
