Multiple active Flash Player installs on Mac, only the first one is detected

====

After a lot of debugging I've found that it is possible to have more
than one version of flash installed on a Mac laptop using Safari for
some reason. This may happen on other Macs and with other browsers,
but the flash player detection routine in SWFObject fails to detect
the correct version. I've made a small modification to the ua
function() section that will correctly detect the most recent player.

Here is the diff for the new version 2.1:
40,45c40,52
<                    d = nav.plugins[SHOCKWAVE_FLASH].description;
<                    if (d && !(typeof nav.mimeTypes != UNDEF &&
nav.mimeTypes[FLASH_MIME_TYPE] && !
nav.mimeTypes[FLASH_MIME_TYPE].enabledPlugin)) { //
navigator.mimeTypes["application/x-shockwave-flash"].enabledPlugin
indicates whether plug-ins are enabled or disabled in Safari 3+
<                            d = d.replace(/^.*\s+(\S+\s+\S+$)/, "$1");
<                            playerVersion[0] =
parseInt(d.replace(/^(.*)\..*$/, "$1"), 10);
<                            playerVersion[1] =
parseInt(d.replace(/^.*\.(.*)\s.*$/, "$1"),
10);
<                            playerVersion[2] = /r/.test(d) ?
parseInt(d.replace(/^.*r(.*)$/,
"$1"), 10) : 0;

if((pv0>playerVersion[0])||(pv0==playerVersion[0]&&pv1>playerVersion[1])||(pv0==
playerVersion[0]&&pv1==playerVersion[1]&&pv2>playerVersion[2]))
{
>                                            playerVersion[0] = pv0;

>                                    }
>                            }

Hope this helps other people with Flash detection on the Mac.

I can't reproduce the issue.

My tests include:
- Mac OSX 10.4.11
- Firefox 3.0
- Safari 3.1

Test sequence:
- uninstall fp 9.124 using Adobe uninstaller
- install fp 8.24
- install fp 9.16
- install fp 9.115
- install fp 9.124
- install fp 9.16
- install fp 9.124

During every version I checked which version was detected by Flash and 
SWFObject, and
which version(s) was installed by the 2 browsers.

However no anomalies.

I can imagine that this can be caused by potential plugin switcher software or
corrupt installers (see FAQ). 

Because I can't reproduce it AND it's the first time I have heard of this 
issue, I am
going to close it for now. 

If anyone can come with more info or can reproduce this I am happy to reopen the
investigation.
