Presentation saved as html distorts images on Vista but not on XP

I'm not sure what newsgroup to post to since I'm not sure what is causing
this issue, so here goes. I use IE7 on both a Vista and XP machine and have a
Web site with PowerPoint presentations saved as html pages. The screen shot
images on the presentation saved as html on the Vista machine are extremely
grainy now; however, they displayed fine a week or so ago. They display fine
on the XP machine. The only thing I did in between was a Vista Windows
Update. Try downloading
http://gdpkeyboarding.com/PowerPoint..._Resources.htm and
looking at the screen shots in Slide 1, Slide 2, Slide 14 (particularly bad).

I posted a page to explain what I'm seeing which hopefully clarifies the
question and issue. If the same images display in the browser differently on
Vista vs. XP, wouldn't this issue be related to a browser setting? It's the
same image, same browser, same html presentation, just different operating
systems. Please have a look at http://gdpkeyboarding.com/ScreenShots.htm to
see what I'm seeing in terms of the degree of distortion. Also, on my Vista
machine, the images display fine within PowerPoint but are distorted as soon
as they are viewed in the html presentation. I wrote comments above the
screen shots.

Thanks in advance.

I tried republishing a test page as follows: File, Save As, Other Formats,
Save as type—Web Page (*.htm; *.html), Publish button, Web Options button,
Browsers tab--check Rely on VML for displaying graphics in browsers, OK,
Publish. PowerPoint appears to also check Save new Web pages as Single File
Web Pages in the Browsers tab even though I didn’t check that box.

When I published with these settings, the display of graphics is no longer
degraded—take a look at
http://gdpkeyboarding.com/PowerPoint.../slide0001.htm
.. This page was saved as New.htm so I’m not sure why the browser converts the
URL to the one you see. In any case, what does “Rely on VML for displaying
graphics in browsers� do exactly? As I said in my previous post, these pages
used to display fine without this setting, but I’m willing to go back and
republish each presentation I have (and there are about 16) using these
settings if that fixes it.
