Impossible, unless there is a deviation in the program code from the recommended usage or creation and release of fonts.
It does not matter whether the font is Public, Private, Local or Static variable
In a well written program, there should never be a need for workarounds like:

Code: Select all | Expand

Do While oFont:nCount > 0
       oFont:End()
   Enddo

Can anyone please provide a small sample to reproduce this problem?

I tested in several ways and never got this problem.
This is one of my tests:

Code: Select all | Expand

#include "fivewin.ch"

MEMVAR oFontP

function MaIN()

   local oWnd, oBar

   PUBLIC oFontP

   DEFINE FONT oFontP NAME "VERDANA" SIZE 0,-14

   DEFINE WINDOW oWnd
   oWnd:SetFont( oFontP )
   DEFINE BUTTONBAR oBar OF oWnd
   DEFINE BUTTON OF oBar ACTION ShowDlg()

   ACTIVATE WINDOW oWnd

   RELEASE FONT oFontP

return nil

static function ShowDlg()

   local oDlg, oBrw

   DEFINE DIALOG oDlg SIZE 400,200 PIXEL TRUEPIXEL FONT oFontP
   @ 20,20 XBROWSE oBrw SIZE -20,-20 PIXEL OF oDlg ;
      DATASOURCE { 1,2,3 } AUTOCOLS ;
      FONT oFontP ;
      CELL LINES NOBORDER

   oBrw:CreateFromCode()

   ACTIVATE DIALOG oDlg

return nil

hi,

i have figure out that "Problem" was in MENU which called DIALOG

for MENUITEM i want a FONT so i use

Code: Select all | Expand

   oMenu:oFont := oFontDefault

but when close PopUp-Menu it will destroy FONT assign to oMenu:oFont

so i need to define a own FONT for MENUITEM

Code: Select all | Expand

   DEFINE FONT oFontMenu NAME "Lucida Console" SIZE 0, - SP_nFontSize()
      ACTIVATE FONT oFontMenu
   END FONT
   oMenu:oFont := oFontMenu

now it work without Error

sorry for my Mistake
