I posted the game using pgnlast tags, however, I see the penultimate move highlighted (and position shown) instead of the last move.

Thanks, should be fixed now.

Pressing the '-' key doesn't do anything around here.

Here's a game with variations higher up in the move list. They should be in green text, in [brackets]. When you've selected the game widget, the - key will fold and unfold the variations. This might only be on a US keyboard, but I don't think so.

I posted a PGN with many games, and nothiced a buggy thing, and a possible improvement of behavior.

The first:



(note I'm at 800x600 res)

The << < + > >> arrows seem missing. Also, the scrollbar going down seems to be cut off.

The improvement on behavior is having it remember what game one is seeing, currently, a ... appears at the top, and if one e.g. clicks on the third game, after clicking the box again ... is highlighted instead of the third game, so navigation is hard as one would need to memorize what game was previously clicked.

The << < + > >> arrows seem missing. Also, the scrollbar going down seems to be cut off.

Yes, this usually happens when they are multiple games. I usually end up having to use the arrow keys to reach the game's end in some cases.

Okay, so this isn't exclusive to 800x600 res

Thanks for the report, I'll check it out.

how to add board coordinates in pgn4web board generator? pls help

Hello, I had a look at the updates you did on the pgn4web code to add variation support.

I found a couple of bugs, that might affect your forum also:

1) mistakes in the PGN syntax are not handled gracefully, for instance this games trows a javascript exception and does not display anything at all:
See:

[White "someone"]<br> [Black "other"]<br> <br> 1. e4 c5 ( c4 ) 2. Nf3 *

2) some comments are lost, for instance the word "try" is lost from this game:
See:
[White "someone"]<br> [Black "other"]<br> <br> 1. e4 c5 ( { try } c6 { instead } ) 2. Nf3 *

OK, both of those problems are "fixed" (the second one really, the first one is just kind of fixed (throws errors because the PGN is bad, but loads the board and lets you begin to debug your game). I'll look more closely, time permitting, at a better solution for invalid PGN data.
