I have the same problem, but am unable to install the hotfix. I get the
error 'The expected version of the software was not found on the system' The
software is on the system as well Office XP.

Can you help please.

Microsoft Knowledge Base article kb938538
(http://support.microsoft.com/kb/938538) describes a hotfix that helps this
situation. Contact MS Service, and they will email you a link to the hotfix
file.

The hotfix improves the performance problem of Excel 2007 charts with large
data sets (as if 8000 points is a lot), but the performance will not come
close to matching that of Exec l2003.

Hi,
I am having a real problem with Excel 2007 (and PowerPoint 2007) when
trying
to manipulate very basic scatter plots (two series, smoothed lines, 8000
data
points per series). When I try selecting one of the series, Excel goes off
in
a huff for about 20 or 30 minutes (I am not exaggerating! It "...is not
responding" for that period and loses the frame it normally has, replacing
this with a standard Window title bar superimposed over the normal Excel
2007
one, until it gives back focus) and then repeatedly becomes non responsive
when trying to manipulate any of the properties (line colour, line style
etc). I have tried repairing Office 2007 and have even tried completely
uninstalling and then reinstalling the program set (but have not "cleaned"
the registry of Office entries after the uninstall and therefore still
have
all my preferences on reinstallation) but that has not changed anything.
If I
do not try to manipulate this type of chart, Excel 2007, and the other
Office
programs behave well. I have saved the file to an xls file and can happily
open and adjust the chart to my heart's content with no issues using Excel
2002 (running on a lower spec machine).
Is this an issue with Excel or perhaps a compatibility problem (I am
running
Office 2007 on a Toshiba Tecra M5 laptop with a 2+ GHz Core Duo and1Gb
RAM,
with Windows XP SP2)? Is there any way I can tell what might be / is
causing
the problem? Are there any simple solutions I can try? Or do I need to
rebuild my laptop installation from scratch (something I am very loathed
to
do!)?
Any hl would be very welcome... if I hadn't lost my hair already, I would
be
pulling it out by now!
Best wishes, Boris.
