I noticed that it took awhile for the server to initially respond, but 
then the page and its content loaded normally.

In the SWF, the scaling of images and the overlaying of multiple scaled 
images with alpha transparency is computationally expensive. The loading 
seemed fine, but all those multiple alpha levels are slower than 
unscaled images or non-alpha overlays.

The "click to activate" was introduced in Microsoft Internet Explorer 
for Windows XP, Service Pack 2. For OBJECT, EMBED, and APPLET tags in 
the HTML itself, no interactivity will be available until the user 
follows the instructions and clicks. You can avoid this by writing in 
the tags dynamically from an external JavaScript file. More info here:

If you're using Internet Explorer and do *not* see this "click to 
activate" on in-page tags, then that could indicate that the computer is 
not yet using XP SP2 or better, and I'd strongly recommend updating the 
system for security reasons.
