Page N of M incorrectly localized

Question

Background : ASP.Net web site running 2.0 / 3.5 framework on a Windows 2003 Server with Crystal Reports 2008 runtime deployed to it. We're running a Crystal Report and exporting to PDF and streaming that to the user. We handle multiple languages so we cast the current thread to the browsers accept language on BeginRequest.
We just got a new server and deployed everything to them and for some reason the "Page N of M" special field page numbers are getting localized incorrectly. English users see "Página" instead of "Page". Japanese and Spanish users don't see the word at all and instead see "1/11". These are fields that Crystal Reports are localizing entirely on it's own - we don't have any special page formulas or anything - and we're at a loss as to why it's localizing it incorrectly. The same exact code is working on our dev and test servers just fine though so we're pretty sure it's not a code problem. Maybe something didn't get installed right or one of  the Crystal Reports resource files got corrupted on installation? Has anybody ever seen this happen before or is this a known bug that's hotfixed?

Answer 1

To review what we've found so far - If I iisreset the website and recycle the Application Pool that the website uses and then request a report in English then I get a report with English page numbering. If I change my browser language to Spanish and request a report then I get Spanish page numbering. If I change my browser language back to English and request a report then I still get Spanish page numbering. The page numbering stays in Spanish until some undetermined amount of time has passed or if I recycle the application pool.
Note: in our Global.asax we cast the current thread to the browser's request language for localization.
Here's what our report export code looks like. We're already using Close and Dispose.
           With crReport
                .SetDataSource(dsData)
                .DataDefinition.FormulaFields.Item("0Title").Text = "'" & strReportTitle & "'"
            End With
            Dim streamPDF As System.IO.Stream = crReport.ExportToStream(ExportFormatType.PortableDocFormat)
            Dim intFileSize As Integer = CInt(streamPDF.Length)
            Dim byteBuffer(intFileSize) As Byte
            streamPDF.Read(byteBuffer, 0, intFileSize)
            Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache)
            crReport.Close()
            crReport.Dispose()
            If Response.IsClientConnected Then
                With Response
                    .ClearHeaders()
                    .ClearContent()
                    .ContentType = "application/pdf"
                    .BinaryWrite(byteBuffer)
                    .Flush()
                    .End()
                End With
            End If
