Scanning through the 3 MiB of source code, I am sure the browser sniffing constitutes a large portion of it. > From the .js >> if (!window.qx) window.qx = {}; > > Wouldn't the following better? > var qx; > if(!qx) { > qx = {}; > } Of course it would. Only a neophyte or fool would risk augmenting a host object like that referred to by `window'. If you are not concerned about statement order reflecting execution order, you could even do if (!qx) { var qx = {}; } and save one maintenance step (see ES3, section 10.1.3, and ES5, section 10.5).

Much better. It's a somewhat minor detail, but a good indicator of bad things to come.

The new version works off a so-called build release of the app, puts everything in one file (1050kb). Loads in 1-2s for me lotsa places. Trying the Mac next. kt -- http://www.stuckonalgebra.com "The best Algebra tutorial program I have seen... in a class by itself." Macworld
