Unity Editor + Laptop + Tethering

Hi everyone,

This is gonna sound strange.

I got a used laptop with Win7 few days ago, installed the newest Unity and enjoined making games. Until I couldn't. The Editor became barely responsive.

After many back and forth I narrowed down the problem to one thing. It only happens when I use tethering (internet sharing) from my phone.

At first I thought it might be a faulty USB controller but I tested with USB headphones, coping data from a USB Pen and nothing. Even the phone can be connected via USB, I just can't turn on tethering.

Yesterday a friend on mine wrote to me about a similar problem and after describing to him what I experienced he discovered the same issue (Unity almost non-responsive after turning on tethering on the phone).

As far as I can tell only Unity is affected. The CPU i at 5-10% and the memory is only half-used.

Did any one noticed something similar or knows what can be done?

PS: I't only the Editor, exported EXE works like a charm.
