Changing Messages from ZOHO

Changing Messages from ZOHO

How can I modify the "Data Updated Successfully" and "Please Wait". 

I have a slow DSL connection, and when I change the information in the database, the messages cover a large amount of the data and I am forced to wait until they disappear before continuing. I know I must wait until the change is actually made, but if I could see the data while it is being changed, I can be planning what to do next.

I looked on the Internet with this question and your site says to open DASHBOARD and then FORM PROPERTIES. When I do that, there are no Form Properties. Only Backups and Usage Logs.

I am not skilled in the actual language, so need a WYSIWYG solution.

Thanks
