Hi,

With a client of outs we are having issues with xBase++. 
When a lot of GUI interaction is done the program just hangs.
For instance we have a xbpListBox created as follows:
  lbFonts             := XbpListBox():new(oDlg:drawingArea,,{320,55}, {300,175})
  lbFonts:tabstop     := .T.
  lbFonts:create()
  lbFonts:itemMarked  := {| uNIL1, uNIL2, self | oFontPreview:setFontCompoundName('12.'+lbFonts:getItem(lbFonts:getData()[1])) }

After creation we add items:
  For z := 1 to len(aThisFont)
      lbFonts:addItem(aThisFont[z])
   Next

This works fine on our machine, but at the client the program will hang.
When we add a sleep(2) in the loop the program runs fine.

This is just one example of a part whee the program hangs. But it will hang on other places in the code as well randomly.

Our client is using Windows Server 2016 with Citrix.

Best Regards,
Eelko.
