I can't help you much with this except to say that there are a number of
peculiarities appearing in Vista and there is little chance that older
versions of the tools will ever be 'repaired'. I'm using Builder6 still for
supporting applications which customers are now simply expecting to work on
Vista - but have the sort of quirks you are describing. I HAD set up a Vista
machine here to play with, but it was SUCH a pain that it has XP on it again
now. Trying to support FOUR incompatible versions of windows is the nightmare,
so at present Vista is off the list. I've just had to wipe an XP machine back
to W2k for a BIG site that has yet to even consider XP. The cost of replacing
several thousand machines with hardware that could RUN XP is simply a joke,
and now of cause the target is supposed to be vista :(

Jason - what are you doing about this in the 'day' job?
