Instead it will end up like this: "hello youare how" or "wt di you say?" This may also be due to the user thinking they made a typo and though not actually seeing it, trying to edit it out while the browser is frozen for a while or loading heavily so that the text being type can't be seen, and not editing in the area where the typo actually was. Reproducible: Always Steps to Reproduce: 1. Open up firefox. 2. Try opening many graphic heavy websites and chatting in a chatroom using digichat technology such as kidschat.com and talk to one of your friends there. People typically flood that chatroom and it will delay the text being typed to your friend and the text will come out incomplete or jumbled, especially if you try to edit the wording while the page is stuck loading the flooded information in the main chatroom there or when it is under a heavy load filled with many users chatting to each other in the main chatroom. Actual Results: Jumbled or incomplete text. Expected Results: For the text to be completed and in the order I had it typed. Note that that room is typically filled with obscenities and is not moderated despite being a kids chat and despite my repeated attempts to become a moderator there so that the kids there wouldn't have to be exposed to that evil.

I don't see the bug with this testcase. Do you?

Given digichat is Java software, this is presumably a dupe of bug 256763, which is also about heavy java use causing jumbled up text.
