I am trying to reproduce this issue so we can fix it but haven't been able to yet. I have a follow up question so we can do more investigating if you don't mind...
What Slingbox model are you using? All the current and past Slingbox models can be found here.
Product Manager @ Slingbox
I have the solo --
the issue is on both chrome and firefox
just to see what would happen I reset my sligbox -
The remote comes up correctly on firefox on mac os
comes up as a traditional remote ( without the abcd and with tivo grayed out) on the web in windows 7 firefox and chrome
I loaded the desktop app (2.x) and it is working correctly on that one.
Thank you for looking at this
