Netscape 6 (MacOS X): The first game goes fine, but when you try to play again by clicking "new game," the "right color: and "right place" boxes do not display the player's feedback! If you "super-reload" everything works normally again.

Explorer 5 (Windows 98), internet play only: As soon as you click on any of the peg holes or placement pegs, anywhere from 1 to almost all of the peg hole images disappear and are replaced by the "missing image" icon. When you click on the "evaluate" button, one to three of the peg images from the guess you just made disappear in the same way. The oddest thing about this is that the pegs affected are usually not the ones being manipulated by the code; the function called by clicking on the placement pegs, for example, only sets the value of two variables, displays a message in the message box, and alters the source of an image which is not affected by the bug (the on/off indicator). Yet calling it frequently causes almost all of the peg holes to drop out.

Netscape 6 (MacOS X, Windows, Linux) and Safari (Mac OSX): Attempts to load this file cause the browser to either hang, or to run so slowly that it seems to be hung or crashed. Very little research has been done on this problem since recovery from it can be such a pain (when testing in OS X one time, i had to forcibly shut the power off to escape). Once i left it to "think" for about an hour (in OS X), and when i came back there was an alert that said something like "Script elements on this page may cause Netscape to run slowly. Do you want to continue executing scripts on this page?" or something to that effect.

Explorer 5 (Windows 98), local play only: The onLoad event handler for the tile images (line 102) doesn't execute at all, so the game never starts.

No problems... yet :)
