I have a remote PC that runs a SQL database. When I click on an item to edit it, I cannot see the dialog it opens from the Viewer. If I do this at the remote PC I can see this dialog. Oddly, I can see the dialog windows open on the thumbnail for the Viewer session, but not from within the Viewer control session.
The host is a Windows 7 Pro PC, the Viewer is a Windows 10 PC. Both are new installs and use version 7.1.2 on the client.
This issue is most likely caused by some factors specific to the Windows 7 OS. Could you please try enabling the Capture alpha-blending windows feature as described in this guide and see if this helps to resolve the issue? In addition, please note that we've deleted your another post in order to avoid duplication.
