SPRESIweb 2.8 needs Firefox or IE Version 8 web browser to work

InfoChem have recently upgraded the SPRESIweb software to version 2.8 This has had some unfortunate effects on web browsers access:

* Internet Explorer (version 6) has a missing search box, seemingly due to access through the CDS site. Version 8 appears to work correctly
* Safari, Opera and Chrome all have a search button that does not respond
* Currently Firefox and IE (V8) are the only recommended browsers to use on Windows, Mac and Linux platforms)

We have notified InfoChem and will keep you informed.
