It is my feeling that System status messages shoud not be in the MAIN FRAME where users data appears. And since you have the conformation pop-up reminder, if the data wasn't saved. I believe a Change Accepted and the like is a nice things to have but should not appear in the middle of the page.
Would it be possible for you to MOVE the Red "ERROR Box" and the Blue "Information box" for changes accepted and the like to the status area or better yet down to the FOOTER LINE.
I wouldn't care if it over-wrote the STATUS BOX or overwrote the FOOTER LINE with anything necessary and then change back on the next screen update.
But having these messages in the current location moves the active page down 4 or 5 lines and forces information off the screen and requires the user to scroll when they normally wouldn't have to.
It would be nice to keep these system messages off the MAIN PAGE so the developer has control of MAIN FRAME. Just a suggestion but one I would love to see. Thanks.
