With my Win 7 x 64 Laptop I had some problems with Wireless adapter when 1489 was on. The start up was greatly delayed and sometimes when I resumed from hibernation the adapter hung and I had to restart. I reverted to 1483 and have not faced such issues so far…
If there is any diff 1489 has brought in regards to control of Network interfaces / wireless adapter , the developers may consider looking at it again please.
Thanks…
