I am having issues with my screen share on adobe connect as a participant. I have just upgraded to windows 10.
When i click share, others are only getting a black screen. They can see my mouse cursor moving but nothing else. When i pause and annotate, they can see my annotations.
When i change to application share they see a black box with a line around it.
I have just changed my gpu, and all the drivers are up to date, so I'm not sure whats going on.
I'm guessing here that perhaps you're trying to share an Office doc and maybe some portion of your Windows 10 upgrade could have also updated some portion of your Office installation (e.g. using Office 365 auto-update)?
If you are trying to share the screen of a Microsoft Office document protected with RMS (their digital rights management anti-piracy aka DRM), for example PowerPoint, then a black screen is normal... because it's not allowed by Microsoft's RMS-DRM.
Basically, any version of Office 2013 or higher, including Office 365, Microsoft's RMS/DRM will give a black screen upon sharing and specifically when trying to mockup (e.g. using Pen mode in PowerPoint etc).
Try downgrading Office to 2010 or lower (strongly recommended!).
OR, once the document is launched do NOT touch any settings such as allow Edit, and do NOT click the warning about documents being unsafe as downloaded from the internet etc... just hide the toolbar, and you will be able to share the screen. Unfortunately for mockups (e.g. Pen mode), you will NOT be able to use anything built-in to PowerPoint 2013/365, you'll need to use a 3rd party tool -- or else the screen will black out again.
Hope this helps.
p.s. Feel free to tell Microsoft how you feel about this "feature" of their RMS, as it's a major issue for all remote presenters.
