I reckon this is because there's some Javascript chundering away in the background on whatever page you've got loaded. I had a similar problem when I added a news-ticker to my Beermad site. Because I have a local copy of the site running on my N800, the news-ticker ran all night after I'd finished using the tablet. Or at least for as much of the night as it took to run the battery down. I don't think this is a bug in the browser as such, more a side-effect of the CPU used by Javascript on a device with limited battery life. The only answer I could see on the browser side might be if it stopped running embedded Javascript when the device was locked (or perhaps when the display had timed out). But then other people might have a reason why they need it to keep on running. -- Tony Green Ipswich, Suffolk, England http://www.beermad.org.uk/ http://www.suffolkcamra.co.uk/pubs/ * No Micro$oft products were used in the generation of this communication _______________________________________________ maemo-users mailing list maemo-users@xxxxxxxxx https://lists.maemo.org/mailman/listinfo/maemo-users
