If anyone out there uses Xilinx ISE Design Suite 11, I need your help!!

According to this information http://www.fpgarelated.com/usenet/fpga/show/662-1.php
ISE 11 should be running verilog 2001, however when I try to run the arithmetic shift ">>>" it does not populate 1's for negative numbers as it should.

Does anyone have any advice on how to correct this problem?
