My surveillance never launches consistently from explorer. Does anyone else have this issue?
I now it's been a while, but do you still continue to have problems with your DNS-327L? I have a similar problem with a unit my friend has, he is using IE 11 on a Windows 8.1 desktop, using F/W: 1.02 from the US support site. The problem seen in our side is that the add-on would launch but freeze at times.
Let me know if you found a solution to your problem, I'm afraid they may be related.
