Before going in to work today I have managed to fix one of the JavaScript problems (it causes MSIE to report ‘one error on page’), but only half-fixed the other (which causes artists’ names with links to vanish when you cycle through the panels). In the latter case, the name no longer vanishes, but, alas! the link does.
I think need a JavaScript debugger—in other words, to install Mozilla on my PowerBook (the only computer I own with enough welly for Mozilla). Ho hum.
