If invalid data is sent repeatedly from a IRC server to a LeafDigital LeafChat IRC client, the program will stop responding. Restarting the application will be required in order to regain normal functionality.

|
*
|
|
* When the LeafChat IRC client recieves invalid data from the server, it
|
|
* displays a dialog box with an error message. Should the server rapidly
|
|
* send invalid messages, the system soon becomes dangerously low in
|
|
* resources and commits harikiri. :-)
