Hello,
I have a problem with a project I’m building. The working swf is at
http://illusionary-amalgam.com/work_related/file01.swf
It currently has the following listeners active. When you click a blurb, you will zoom into it. When you click it again (or anywhere on the flash object) it will zoom back out. If you let it idle it will zoom in and out at roughly 10second intervals.
There are also keyboard functions that when you click on the arrow keys it will move the camera in various ways. The keys only work in the zoomed out state and are disabled on zoom in.
The problem that I’m having is with these. On startup, the keys work fine. If you let it idle and have it automatically zoom in then out, the keys will work fine. However, if you manually click out of a blurb, the keyboard event listeners stop working. I’m not sure why this happens since both the auto-zoom and the manual zoom both call the same function to zoom out.
At first it seems to be that the window is losing focus, since if I click on white space I can use the keyboard again. The problem though, is that when I use an DEACTIVATE event listener to test it, it doesn’t show the flash object losing focus. Because of that, I’m not really sure how I would go about fixing this problem.

Thanks in advance.
