Resizing Crystal window opened via API loses the controls at the top of the page

I am using VB6 and Crystal Reports 9.0
I am using the API calls in crpe32.dll for all of my reports
The following code works, but when the report window is resized, the controls disappear

  Dim sPath As String
  Dim LogOnInfo As PELogOnInfo
  Dim TableType As PETableType
  Dim sTemp As String
 
  sPath = sReportPath & "Report.rpt"
 
  result% = PEOpenEngine()
  If result% = 0 Then
    MsgBox "Could not open print engine"
    Exit Sub
  End If
 
  jobnum% = PEOpenPrintJob(sPath)
  errorcode% = PEGetErrorCode(jobnum%)
  If errorcode% <> 0 Then
    result% = PEGetErrorText(jobnum%, textHandle&, textLength%)
    ' Get the text from the handle
    ErrorText$ = String$(textLength%, 0)
    result% = PEGetHandleString(textHandle&, ErrorText$, textLength%)
    ErrorText$ = Trim$(ErrorText$)
    ErrorText$ = Left$(ErrorText$, Len(ErrorText$) - 1)
    MsgBox ErrorText
  End If
       
  TableType.StructSize = PE_SIZEOF_TABLE_TYPE
  LogOnInfo.StructSize = PE_SIZEOF_LOGON_INFO
 
  result = PEGetNthTableType(jobnum, 0, TableType)
 
  LogOnInfo.ServerName = sServerName
  LogOnInfo.DatabaseName = "AB"
  LogOnInfo.UserID = "sa"
  LogOnInfo.Password = ""
         
  result = PELogOnServer(TableType.DLLName, LogOnInfo)
 
  Dim crdev As crDEVMODE
  Dim sD As String, sP As String, sT As String
 
  sD = sWorkDriverName
  sP = sWorkPrinterName
  sT = sWorkPrinterPort
   
  handle = crPEGetSelectedPrinter(jobnum, sD, sP, sT, crdev)
  handle = crPESelectPrinter(jobnum, sWorkDriverName, sWorkPrinterName, sWorkPrinterPort, crdev)
   
 
  'Print to preview window
  If sOutput = "P" Then
    result = PEOutputToPrinter(jobnum, 1)
  ElseIf sOutput = "S" Then
    result = PEOutputToWindow(jobnum, "Report", 0, 0, IIf(FrmMain.ScaleWidth \ Screen.TwipsPerPixelX > 860, 860, FrmMain.ScaleWidth \ Screen.TwipsPerPixelX), FrmMain.ScaleHeight \ Screen.TwipsPerPixelY, 0, FrmMain.hWnd)
  End If
 
  If result <> 1 Then
    'DisplayPrintError result, PRJob
 Else
   
    'Start print job
    result = PEStartPrintJob(jobnum, True)
  End If

  PEClosePrintJob jobnum%

frmMain, which is passed into the PEOutputToWindow() call above is my MDI parent form.

p.s. This code was ported directly from a previous Crystal Reports 7.0 project and resizing worked fine.

Thank you in advance for any help.
