[SOLVED] Altium 15: from tos line persist. Any off-screen component?

Hi all,

I've a problem with Altium 15 at the end of PCB routing:

Once routing was done, a "from-tos" line (one ratsnest) remain on the screen. It link an object connected with VDD (smd pad, or also a with a via through power plane (VDD)) with something that resides off-screen. No way to see what kind of object is because the line go away from screen.
See the 2d view:

With 3d view the line has an end but it doesn't point anything.


How could I resolve?

I've just found the error with the help of DRC. It seems a net on the Multilayer that must be connected with VDD but...why? The result of DRC is a set of 3 errors:

-Net Antennae: Track (-17.772mm,-27.5mm)(3040.717mm,-2745.076mm) Multi-Layer
-Net Antennae: Track (-17.772mm,-27.5mm)(3040.717mm,-2745.076mm) Multi-Layer
-Un-Routed Net Constraint: Net VDD Between Pad C32-2 (205.65,18.25mm) And Track on layer Multi-Layer (3040.717,-2745.076mm)

Probably it happened initially, when I moved the "rooms" on the board. But now, how can I delete or fix this issue?
Any idea?

Finally the issue was solved!
I hide all layers except Multilayer then, in PCB editor, I went to edit->select->outside area and I drawn a rectangle over the board. Finally I moved the line on Multilayer layer and I've cancelled it.
