Note fields memorizing

Hi,

I noticed something :
When writing a mail for example, the dialog window keeps information when we close / re-open it.
A good thing, If we need to check something on the ticket to be sure while writing.
But with the note dialog window, if we close it, then re-open it : the form lost all the informations we started to write ...

Could it be possible to memorize the informations ?

Thank you in advance,
Regards
