Confused over demo

Hi all, I'm working through our demos at present. Firstly, I've apparently a handful of .dlls that need updating before I can look at imgbrowser.php, but that's neither here nor there (tho' I'm confused as to why my pixbufloaders are asking for something more recent than the .dlls that came with them). So I'm glad that demo's there, because otherwise I wouldn't have known I needed to upgrade those .dlls :) Secondly, I'm very confused about gtkwindow.php. What's it actually intended to do? It loads up saying 'Click the button!' but the button's not connected to anything, so clicking it does nothing. It has a popup window lurking behind it, full of 'unsupported types'. I'm not at all sure what it's supposed to be demonstrating. Perhaps someone could post me a screenshot of what it does under *nix? Thirdly, we still have two stock-browser demos in there. We should lose stock-browser2.php if it's just a copy of stock-browser.php, no? Moving on to tests... - Steph
