Problem exporting queries.

I have some normal and some custome queries that I want to export in CSV in order to set them nice and presentable in an excel sheet.

Now the problem I am having, is that the report generates about 10.000 lines, and when I export it, it only transfers the first 4000 lines.

As you can see, this is a very anoying problem, and truth is I have no idea why is it happening, and don´t know if there is a way to walk around it. I asked several guys over here, and no one seems to have a clue.

Any chance someone here knows a trick?

BTW, Opscenter 7.5.0.4
