Bug - Some Shortcuts can't be fenced

I have a couple of shortcuts that refuse to be fenced. That is, I drag them into a fence and they stay where ever I drop them. Unlike a regular shortcut which the Fence "grabs" and moves to the next position. Then if I move the fence, I see that the fence and other icons move both those few remain where I placed them. That is, they really were on the desktop all along.

For example, this shortcut: "C:\Program Files\ibm\Lotus\Symphony\symphony.exe"

refuses to be fenced.

And here is a shortcut: "C:\Program Files\RegistryFix\RegistryFix.exe" that works fine.

I see no difference betweene the two except that the one that doesn't work has more subdirectories.

Thanks,
