very similar to http://www.rockbox.org/tracker/task/9383:

1. start the game with 3 or more players.
2. delete one of them i.e. p3.
3. the time is now running for p1.
4. press right to go to p2, press it again and the player is frozen.

some more things:

if you start the game with 0 players, it still creates one player.

with the e200 you can increase the number of players with the scrollwheel to 1, any further scrollwheel actions are ignored.

you can start a "game" with 0 players (it still creates one), max time=0 and max round time = 0, which makes no sense.

if it says TIME OUT and you go to the menu, select total time and press select, it shows "total time" and below this "TIME OUT!"

if it says "TIME OUT!" and you go to the menu, go to a random menu-option and then press power to quit the menu, it'll show the menu point (i.e. delete player) and below this "TIME OUT!"

if it says time out and you select round time in rthe menu, it says (very short) 00:-4. sometimes also -5 and -7 appeared. i also saw -1:-4, it seems to be random. then it says as expected "rount time 00:00 (m:s)", if you presss select, it shows again the random numbers.

if you go to the menu while the time is running, wait 5 secs and then select restart round, it'll start from the round time - 5 secs (i.e. from 15s when the round time is 20s). if you dont wait in the menu, it'll show the right time.

the backlight will turn off after the default time (while the chessclock-time is running), and go on again after ~secs.

the down-button-actions are very strange sometimes nothing happens, sometimes it adds 8secs, after the time is out it adds 25 secs, a second press will set the time to 27 secs. if you press it a few times in a row, it'll remain a few second at the 27secs and then count down again.

in short: chessclock only works if you do nothing or if you only use left/right to change the players :)
