Hi Harlan
Where to begin?

first I was afraid for what might follow :-)


It installs OK under XL97SR-2 under Windows NT4SP6.
Good (Bob has added a platform table to show which versions work ok)


I created the following conditional formats with cell A1 active.
[...]

It works for static values in A1, but you know me, I like to torture
test. It gives sporadically random wrong results for the volatile
formula

=1/RAND()^2-5

you're not fair :-) - who want to conditioanl format such a formua
<vbg


You're using x.PasteSpecial Paste:=xlPasteFormats, so your code
suffers
from what I consider a bug in Excel: pasting formats or comments into
a
range triggers recalculation of that range. That should be intended
functionality when pasting formulas or values, but unhelpful when
pasting formats. FWLIW, 123 releases 5 and 97 and OOo Calc also share
this 'functionality'.

thanks for this specific error explanation. But looking at the code I
would suspect that it is not this code part but the resetting of the
application.calculate mode to automatic.
Just executing the two statements
application.calculate=xlCalculationManual
application.calculate=xlCalculationAutomatic

will re-calculate volatile functions.


The problem is that this differs from Excel's built-in conditional
formatting functionality. Not good. Looks like you'll either need to
disclaim your add-in working with cells containing volatile
functions,
or use the slow but sure way of setting conditional formats one at a
time rather than using copy & paste. This is at variance to some
private e-mail correspondence between Frank and me, but I wasn't
aware
of this little headache until recently.

As above don't think this would help. So probably a statement in the
help / webpage that it does not work with volatile functions such as
RAND()


Next, either the copy or paste format function doesn't work. If I
select the A1 cell formatted as above, run the menu command
[...]

Yes, a bug. Wrong check procedure at the beginning due to a last minute
change. will work in the next update. Thanks for that spot.
We will also add a note that for complicated conditions copying these
format copying may not work (esp. if you're using relative references
in the condition)


Next, and REALLY ANNOYING! I return to cell A1 and run the menu
command

xld Tools CF Plus Special Functions Highlight ranges

There's garbage now appearing as a drawn object in cell A1 obscuring
the contents of cell A1. This isn't the annoyance for me. If I click
on
A1, I get a dialog showing its conditions. This also isn't the
annoyance
for me (though why there are both OK and Cancel buttons in this
dialog
is a mystery).

Will remove the Cancel button :-)
The 'garbage' is due to using a shape to indicate the used CF cells.
This feature is only a 'nice to have' to show which cells have a CF
applied.


No, what's annoying about this is that if I select some
other cell then click on A1, the dialog appears again, but after
dismissing the dialog the cell pointer is returned to it's starting
point rather than staying in cell A1. On the other hand, if I use
cursor keys to return the cell pointer to A1, I don't get the dialog
and I stay in cell A1. Maybe this is specific to XL97, but REALLY
ANNOYING that *clicking* on cell A1 won't leave the cell pointer at
A1.

Works as designed :-) and also the reason why the cursor keys don't
trigger the message box is also due to using the shape object
But still valid points from your side and depending on other feedback
we may change this behaviour


Also, if you can display formatting in the preview box of the
Conditional Format Plus - Add dialog, you should display something
similar when range highlighting is enabled. The MsgBox dialog you're
currently showing isn't particularly informative

Good idea. I'll check how much effort this would be

Thanks again for your feedback

Frank
