Subject Re: RDP Display Size with IE and Firefox
Date Tue, 19 Jul 2016 04:01:32 GMT
These are the configurations that aren't working:
I've tried Win7, Server 2012R2, and Windows 10
* Firefox 47.0 (Win7)
* Firefox 47.0.1 (Win2012R2)
* IE 11.0.9600.18376 (Win7/2012R2)
* IE 11.420.10586.0 (Win10)

Chrome 51.0.2704.103 works well on Win7 and Win10.
