That probably depends on the GUI (Graphical User Interface) and engine you are using. Sounds like a program-specific bug.
Resolved: Chess against computer

I'm pretty sure that he's talking about the chess.com computer. In this case it is a known bug and the staff are hopefully working on it.

I just guess now: whenever a comp hangs it expects something it doesn't get. So, if the computer is losing and starts to hang maybe it faces a conflict of "resign" or not.

We've just added a fix for the 'against the computer' issues members have been experiencing.
Can you go into computer chess, look on the bottom right corner of your monitor. Can you click on the java icon then Open Control Panel.
Once this is open, use the bottom box where it says 'Settings' - when that new box opens, click where it says 'delete files'.
Then OK
Once you've done this, refresh the page.
Sometimes the java icon is turned off from appearing in the tray. If you're running windows....
start button/control panel/java/advanced/miscellaneous/check box "Place icon in system tray"
Also try clearing your cache, and even your java cache. see: http://www.java.com/en/download/help/plugin_cache.xml
Then try 'against the computer' for me. If you're still having issues on there can you please let me know in detail whats happening.
Thanks
Hi,
For the past 3-4 weeks, the computer hangs as soon as I get to the point of winning the game. Playing against the computer works only if I'm losing. Why is this so?
Thanks,
