Market Share information gathered from various stats web sites and media statements released by stats organisations. They are indicitave only, but the general trends are confirmed by all stats results avaialble. IE market penetration is on the increase. Netscape has been released as AOL6, and as a bug fix incremental release of Netscape 6.1. Current releases of both IE and Netscape support the features necessary to display the Spinner-Scripts sucessfully on most platforms. The older browsers which do not support these scripts are no longer readilly available. It is the considered opinion at this point in time that the potential market will continue to grow through the adoption of current browsers for new users and older versions being replaced.
The minimum browser requirement is Version 4. Earlier generation browsers (of which there are thankfully very few still left in use) do not support the technology required to display these scripts.
** The release version of Netscape 6 (Mozilla18) has been sucessfully tested on the Linux release with only minor speed/response issues and some concern about Netscape's internal image caching and handling. However the Win32 version of the Netscape 6 Release product exhibits very odd behaviour in image handling and lagging event response. Netscape 6 is not considered a reliable prime-time product at this stage, although it looks promising. As of the 21st of November, support has been re-enabled, but the behaviour of the Netscape 6 (Win32) version is erratic, unpredictable and should not be relied on.
*** The security changes made to Netscape 4.76 seems to have blown big chunky holes in it's JavaScript support. If something appears to have stopped responding, reload the page (worst case restart Netscape) and it should pick up again. If this (4.76) is supposed patch a security hole in JavaScript support, I can't help but wonder what other holes it has obviously opened up :-( The problems, which appear to be memory and resource related are worse on Linux than Win systems.
Macintosh issues: IE V4.5 has known issues on the Macintosh platform with mouse-drag being intercepted by the OS. As this is not an issue with Netscape or later versions of IE (eg IE5 for the Mac) it is considered an IE4.5 bug. IE version 5 for the Mac however has a memory management problem when images exceed a certain size. Microsoft engineers have confirmed this is a limitation of the file buffer implemented by IE5 on the Mac platform. They are endeavouring to have this limit increased which should resolve the IE5 Mac problem.
