Just asking again if there is any update on your case.
They have relaeased V 7.3.0 has been released. I have upgraded and there was an imediate reindex after the installation finshed. That took aboiut 26 hours to complete.
I have just rebooted the server and they chagned the text used on the items after a reboot to say A catalog item has been modified XXXXXXXX where the X's are the softpaq id.
its been running since about 11 this morning and is still going right now.
