Thanks for the quick response Sway (I post the tread 3 times because I was using G.Chrome and I wasn't getting the "your post will not be visible..." message until the 3rd time when I post from FireFox, so sorry about that).
Well I'm a C# developer and let me say that this smells like some focus problem.
When I click somewhere on my desktop or when I click an icon and then move the mouse over the gadget, it stays transparent.
But if I click the gadget and move the mouse out and then into the gadget area, it becomes 100% opaque like it should.
My Win7 is also Ultimate and I have applied a lot of updates that where filtered on the internet (all of them digital signed from Microsoft).
I have just tried the gadget on a virtual machine (the same Win7 using VirtualBox 3.0.10) and I have the same problem but I have to say that I also have applied the updates to that Win7 so maybe one of that updates is causing this.
