There's a new version of Spectrum Analyser available on AeroXP.

For the past month, I've been investigating an issue where embedding WMP into a Gadget causes Sidebar to not trust Gadget code.  Obvious symptoms are "Access Denied" errors when Gadgets try to access local files or Flyout/Gadget/Settings variables.  The problem centers around security updates released on the 14th August, notably KB937143.

I've not actually found what the cause is, but removing the update didn't resolve the issue.  However reinstalling it seems to resolve it.  I can only guess that there's either a conflict with other updates or the install is failing in some way, which isn't visible.

I expect this isn't the end of the story, as I'm not convinced this is either the cause or the fix.  I'm fairly certain that something else is coming into play here, that I've missed.  Unfortunately, the problem isn't always easily reproducible, it's a random issue that occurs after no obvious event.

An early workaround I found was to put an invalid "Mark of the Web" in the HTML header.  Although this stopped the issue occurring virtually immediately (playing a stream would immediately brand the Gadget untrusted), the problem would reoccur if a WMP Gadget was left open for any length of time.

If you use Network Utilization, you might want to have a look at Network Traffic, which is based on my Gadget, but with a nifty front end:

And whilst you're on the site, have a look at Volume Control Reloaded, which uses the new Vista Sound API:
