Exporting to PDF within InDesignCS4 makes extraneous copies

Question

I think this is since updating to Snow Leopard 10.6.3 --I frequently export InDesign CS4 documents as PDF files within InDesign. It may only be affecting one particular folder, in fact. I have a folder that I keep about 50-60 PDF files exported from InDesign (all similar documents). Now, all of a sudden, when I export another document as PDF to that folder, I get copies of everything in that folder strewn all over my Desktop. I then have to collect them and trash the Desktop copies. I don't know if this is a Snow Leopard problem of an InDesign problem, but it just started happening a couple of days ago. I just did an experiment and exported one of the same documents to the Desktop rather than the crazy folder and I got just one copy. But if I send it to the same foklder I have been using for a couple of years, I get copies of the whole folder on my Desktop? This is very perplexing to me. The PDF settings in InDesign are for small sized PDFs and compatible with Acrobat 7. I share these documents with others so try to make it compatible with an older Acrobat version just in case.

Here is snippet of code how I am exporting rpt file to pdf file. I didn't include every code here but I am hoping this will give you the idea. Please let me know if you need more info.
public byte[] runReport(RPTParameters para) throws SQLException {
byte[] reportData = null;
ReportClientDocument reportClientDocument = null;
try {               
     reportClientDocument = new ReportClientDocument();
     reportClientDocument.setReportAppServer(ReportClientDocument.inprocConnectionString);
     reportClientDocument.open(ReportDataConstants.CPS_RPT_FILE, OpenReportOptions._openAsReadOnly);
     ExportOptions exportOptions = new ExportOptions();               
     PDFExportFormatOptions pdfOptions = new PDFExportFormatOptions();
     exportOptions.setExportFormatType(ReportExportFormat.PDF);
     exportOptions.setFormatOptions(pdfOptions);
     ParameterFieldController paramFieldController = reportClientDocument.getDataDefController().getParameterFieldController();               
     paramFieldController.setCurrentValue("", "@ba", para.getBusinessAgreement());
     paramFieldController.setCurrentValue("", "ReportMonth", para.getMonth());
     paramFieldController.setCurrentValue("", "ReportYear", para.getYear());
     InputStream reportInputStream = reportClientDocument.getPrintOutputController().export(exportOptions);     
     reportData = new byte <reportInputStream.available()>;
     reportInputStream.read(reportData);
catch (ReportSDKException e) {
finally {
return reportData;
