I often use Libre Office with Visual FoxPro 9 via automation on Windows Server 2019 Std.  When I open Libre Office Writer from VFP using code as shown below.  I am unable to close Libre Office by clicking the X in the top right window or by selecting Quit from the file menu. I can close the document but not Libre Office.  However, the exact same code is used with Libre Office 6.4 and works just fine as I can close the application. 

oMergeSrvMgr=CreateObject("com.sun.star.ServiceManager")
oMerge=.oMergeSrvMgr.createInstance("com.sun.star.frame.Desktop")

laArgs(1)=oMergeSrvMgr.Bridge_GetStruct("com.sun.star.beans.PropertyValue")
laArgs(1).Name="ReadOnly"
laArgs(1).Value=.N.
laArgs(2)=oMergeSrvMgr.Bridge_GetStruct("com.sun.star.beans.PropertyValue")
laArgs(2).Name="Hidden"
laArgs(2).Value=.T.
ComArray(oMerge,10)  && convert VFP arrays to COM compatible array
      oMergeDoc=oMerge.loadComponentFromURL(ConvertToURL(tcFile),"_blank",0,@laArgs)

oMergeDoc.getCurrentController().getFrame().getContainerWindow().setVisible(tlVisible)
     
Thanks,
Simon
