If you are using Build 0300 it's not really worth bothering with 0301
because it only contains changes to the installation notes and a few
dates have been corrected to read "2006". Unless of course you really
want to...
It is probably best to wait for Build 0302 which should hopefully
contain the database engine fix to get the cut, copy and paste buttons
working again. I have read that this is expected in the next few
months...
