Combining or AddCopy Out of Memory exception

I just updated Aspose.Total for .Net, I have this problem before and after the update.
I am using the Aspose 2.0 dlls

I am opening an excel workbook with one sheet called “Temp” which is my template.
I then want to copy it a few times to make copies in the same workbook, then close and save the workbook.

However about the third time I call wb.Worksheets.AddCopy(“Temp”) , I get an out of Memory Exception.

I also tried converting this to open the work book multiple times and them use Workbook.Combine(), and I also get an out of memory exception doing that.

The workbook is only about 10KB, and I have commented out the actual data writing procedures, so there shouldn’t be lots of memory used data-wise.

I am using Aspose.Cells in an ASP.Net development environment.

What am I doing wrong?

I was able to create a list and then use Aspose.Pdf.Kit to combine pdfs.

I traced the problem down to this line however,
ws.Cells.CreateRange(“F:I”).ApplyStyle(dollars, flagCustom);

This operation is expensive for Aspose, I assume because it is formatting every cell in the columns??

It does not run out of memory if I change the line to a limited rowset as shown below.
ws.Cells.CreateRange(“F7:I27”).ApplyStyle(dollars, flagCustom);

I believe this behavior is different than the Interop behaviour for formatting entire columns.
