Strange. As long as you don't click a mouse button, nothing should happen.

Sounds like a mouse hardware problem to me. Worn out button? :o)

Not in the way known i.e. from WB. egines... I know what you mean - an "keep all
the engine's analysis output" log, but the analysis functions of the Fritz GUI
are designed more for the practical player than for computer freaks like us :o).
Usually (some of) the results are put in the notation directly, by the various
types of analysis functions.

I think "Compare Analysis" is the next best to a typical engine log. It keeps
the pv, eval and depth (and nodes by option), but only one per position of the
game analysed.

This is controlled by the "Last Move" value in the full analysis dialogue. F1
help says, "Last move: This sets a limit for the analysis. Analysis always
starts at the end of the game and goes backward, ending with this move." I've
just tested it in the ChessProgram8 GUI. Works... but make sure you have the
latest GUI update for Fritz 7. I seem to remember that there were bugs related
to the Full Analysis in F7. If it doesn't work, try to disable the opening
reference of that function.

No, here the program itself decides what to insert as a commentary, variations
etc. (an award winning AI analysis function) to design something similar to a
human-like master analysis. One of the advantages is, that the engine "goes
into" variations (which it thinks are worthwile to be explored further), playing
through them move by move rather than to just insert a pv.

Another advantage is, that this function can respond to threats and interesting
what if? situations, an "inserting engine's output move by move" method can
never comment on. For example, if there was an attractive move which turns out
to be a deep trap sacrifice, and the player has spotted that trap avoiding i.e
to capture a piece which was en prise, a simple analyis function which sees that
as well, will think all was ok in the game and you'll never be pointed to that
by the output. The same goes for some defensive moves which may seem strange,
but are necessary to defend against threats (which therefore never appear on the
board nor in simple analysis outputs).

But that's completely different of course from traditional engine logs.
