Documents save changes lost when internet connect lost.

[bhwong]

I happen to make some major changes to a document and when I click close, Zimbra prompts me to save it. But as my network has lost it's internet connection, Zimbra simply close my documents without verify if the changes are indeed saved. When my internet connection is up, I realize that all the changes are not save.

Possible to make Zimbra check if the document is indeed saved when user click save before really closing the document for good?
