error 462, vba and powerpoint

[dchman]

I inherited an Access application which is used to prepare a powerpoint
presentation through VBA. Once the user picks a presentation and clicks go,
a powerpoint application is started and a template presentation loaded.
Through VBA, the slides in the presentation are updated with current data,
including charts embedded within the presentation. More often than not,
somewhere in the middle of the process, while attempting to update a chart on
a slide, error 462 will occur in one of the subs. If I trap the error
outside of the sub and just resume, the process will continue without the
error.

Anyone have any ideas on why the error is occurring and how to prevent it?

Oh yeah, one more clue? On my development machine, the error doesn't occur.
The error only seems to occur when the app is deployed to a server, which is
access through a citrix client. Some sample code is given below.

thanks

I did more digging - put Break on Error on VB code - this is one of the real
subs from the app - the error occurs most often in the middle of the
indicated loop -

Private Sub BuildCrossTabByCats(iFirmID As Integer, TypeID As Long)
'Declare object variables
Dim db As Database
Dim rsData As Recordset
Dim rsCats As Recordset
Dim rsPos As Recordset
Dim theChart As graph.Chart

'Declare variables

Dim sVal As String
Dim iSlideCount As Integer
Dim theCharts(0 To 2) As graph.Chart
Dim x As Long, i As Long, posCount As Long, iDataCount As Long
Set db = CurrentDb()
On Error Resume Next
db.TableDefs.Delete "Crosstab Avg of Cat Avg for " &
kCrossTabStrings(TypeID) & ""
On Error GoTo 0
db.QueryDefs("Make Crosstab For " &
kCrossTabStrings(TypeID)).Parameters(0).Value = iFirmID
db.QueryDefs("Make Crosstab For " & kCrossTabStrings(TypeID)).Execute
Set rsData = db.OpenRecordset("SELECT * FROM [Crosstab Avg of Cat Avg
for " & kCrossTabStrings(TypeID) & "] ORDER BY Value")
Set rsCats = db.OpenRecordset("SELECT ShortName, AbrvName FROM [Question
