You should probably keep the set widget, it is generally considered impolite to spam a server with unneeded requests like that.
This should get around the caching problem and not spam the server with requests: \define img(x) [img[http://ichart.finance.yahoo.com/t?s=^DJI#?$x$]] \end <$set name=CurrentTime value={{$:/temp/update}}> <$macrocall $name=img x=<<CurrentTime>>/> <$button>Refresh Tiddler <$action-setfield $tiddler='$:/temp/update' text=<<now>>/> </$button> </$set> That should work without spamming the server. The button will only update the image if at least a minute has passed since the last update. It doesn't happen automatically, but it won't update unless at least a minute has passed. This is because the now macro without arguments returns a string that is only accurate to the minute. This is probably desirable here. You can change <<now>> to something like <<now ss>> if you want to be able to update every second instead. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
