I can not see the family tree of the browser Google crome. Regularly calls for the reinstatement SVG. Where could be the problem?
I do not show the latest photos. Past is visible.

Having had to re-instal everything (system disc dying) I find that both Firefox and IE8 do not display svg without the add-in, so time to try Chrome. This does display the svg pages but not directly. Clicking the icon has no effect; need right click and open in a new tab - or have I missed something? Still can not create a useful report on this PC - have to put it on the web. Have reported this as suggested.

I'm surprised that you are having a problem with Firefox displaying SVG natively, it works very well for me (version 12).  I am not sure now whether IE8 has native SVG support but IE9 definitely has and again works well.

Chrome to has an absurd 'same domain' security policy in that when it accesses pages via the FILE: scheme rather than HTTP: considers files not to be in the same 'domain' as the referring file. This to me is crazy and despite many people complaining no fix has been forthcoming. This is why communication between the different frames of the report is broken. I think the frame pages do get loaded but the frame sizes do  not adjust to reveal them.  I actually run a small footprint local web server, NGINX, to overcome this and access the reports via HTTP localhost.

Just tried Firefox again - and it displays svg now. It is possible thar I tried to use a completely bare installation, before installing Flash Player, which I suspect contains the svg ability. Firefox seems to be issuing new updates every 6 weeks and I am now up to 15.01. Not everything is an improvement. We have large index files, which are derived from a spreadsheet and are displayed with a jpg background. Sometime back (?v.10) the behaviour changed and the background gives up half way down the table. Some people have not heard of 'If it ain't broke...'
Running XP you can not upgrade to IE9 (I think).
Am I correct that Chrome needs to open svg in a new tab? - or is that me again. I have found that I can view any file if opened into a new tab. However although it displays the svg it has a message 'GenoMaps may not display correctly as the required SVG interface does not appear to be supported by this browser'.
Think I will give up on Chrome, although it seems to load much more quickly than Firefox

SVG support is built-in to Firefox so there is no dependency on Flash at all.

I believe you will loss functionality by opening svg in a new tab however  I have just discovered that it is possible to override Chrome's 'same origin' local file security policy by running Chrome with the --allow-file-access-from-files flag.

To do this create a shortcut to Chrome and set target to somrthing like

"C:\Program Files\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files

Your path to Chrome may differ from the above.  This is how it is on my Windows 7 system.

The developers say there is a theoretical security problem using Chrome in this way and suggest the flag is not used when accessing the internet. I not sure how real the risk is.
