This problem happens only with IE9.

 

I have been able to re-create the error on your website using the following URL - http://cutesoft.net/example/oncarriagereturn.aspx

 

Start typing after the "type here" text .  When you press 'enter' for the first time it will not linefeed.

 

This only seems to happen when the curser is at the end of the line and it is the first time you press enter.

 

This is driving my boss crazy and I want to keep my job.  Help please!!!
