This document provides information that supplements the SuperPreview for Internet
Explorer User Guide.
- Fixed position elements
Content with CSS fixed positioning may appear in several places in the SuperPreview
for Internet Explorer display.
Back to Top
- Flash and ActiveX objects
Because SuperPreview for Internet Explorer does not render Flash, ActiveX, or other
object content, a region that contains an object may not be displayed at the same
size as it would be displayed in a browser (depending on the underlying HTML and
CSS). Set width and height dimensions (in pixels) for each DIV tag that contains
an object tag to help mitigate this problem.

- Script-triggered layout changes
Layout changes triggered by asynchronous JavaScript or other Ajax content may not
render.
Back to Top
- Login-controlled pages
SuperPreview for Internet Explorer does not prompt users for login credentials and
so cannot access pages that require authentication, such as those controlled by
an .htaccess file.
Back to Top
- Right-to-left language rendering
Using HTML to set the text direction to right-to-left causes rendering issues in
all browsers.
Back to Top
- Internet Explorer 8 Beta
SuperPreview for Internet Explorer is incompatible with Beta and Release Candidate
(RC) versions of Internet Explorer 8.
Back to Top
- Selectable elements
Children of an HTML element with CSS overflow property set to hidden, auto, or scroll
may be selectable in the SuperPreview for Internet Explorer browser view, even though
they may not be visible in the rendered page.
Back to Top
- Framesets
HTML elements inside frameset pages are not selectable or visible in the DOM tree.
Open the frameset pages individually to display them.
Back to Top
- Timed meta redirects
SuperPreview for Internet Explorer does not follow meta redirects that have a time
interval greater than 0. Instead, navigate directly to the desired page with SuperPreview
for Internet Explorer.
Back to Top
- Element display size for quirks-mode pages
Quirks-mode pages may display the body and html element height and width incorrectly.
Elements inside these tags are unaffected.
Back to Top
- Security certificate errors
Pages that display security certificate errors in a browser will not display unless
the certificate has been approved in the browser.
Back to Top
- Cookie behavior
Cookie behavior is inconsistent between browsers. Because SuperPreview for Internet
Explorer relies on locally installed browsers, it will sometimes read and write
local browser cookies.
Back to Top
- Visited link display
Some links for Internet Explorer may display as "visited", depending on the user's
Internet Explorer browser history.
Back to Top
- Scrollbar display
Scrollbars may not be displayed in some SuperPreview for Internet Explorer browser
views for pages with frames, iframes, or other large, scrollable regions.
Back to Top
- PSD image preview
DirectX must be installed on your computer before you can compare a web page to
a PSD image.
To install DirectX on your computer, visit the Microsoft Download Center.
