I get a phantom window in the centre of the screen when I start X1 Search in Win 10x64. The window is about 1" square and cannot be closed. I reported this as an issue a few weeks ago (Case #00104610). An update today: Task Manager shows 4 processes, X1.exe, X1ContentExtraction.exe, X1ServiceHost.exe and X1Viewer.exe. The window is caused by X1.exe, as killing this task removes the window.
I cannot find another post of a similar problem. Anyone else found a fix for this? My work around is to start windows with the X1indexer running, but not the main interface.
