velbus link has a problem on dual screen setups, when velbus is on a secondary screen (not the primary defined in windows),
if then a popup window/dialog needs to be open velbus link just hangs, the interface is disabled, but the dialog is never shown.
But the log for example stays working …
Most likely, the modal window is displayed, but outside both screens somewhere. For science, you can try ALT+SPACE to try and move the window into one of your screens.
i’m unable to move the window into the screen area, any other fix possible?
Not using dual screens 
to bad, i even use triple screen, …
Just wanted to let you know I just tried this on my dual screen setup but I don’t have this issue.
Also, for science, I’m unable to move the dialog window with Alt + space (Windows 8)
