Good news is that the 5.3.2 update looks like it is OK to take for the Airport Utility. Also I’m now using Entourage 2008 and Excel 2008 and that looks like most problems are fixed as well
Airport Utility 5.3.2 is quite harmless. More people having problem with OS X 10.5.3 update, which is making the AirDisk very slow and unresponsive. I end up re-formating the USB hard disk to solve the problem.
