3.1is6 Foundation ISE - Opening Constraints Editor on a Win 98 system brings up XILPERL:Invalid Switch message


General Description:

When opening the Constraints Editor from Foundation ISE 3.1i in Windows 98,

a DOS Window named XILPREL opens with the message "Invalid Switch."


The customer should be able to safely ignore this message box.

This problem has been reproduced by Xilinx Development and does not

effect the proper function of the constraints editor.

Note: The constraints editor can be opened outside of Foundation ISE

without receiving this error message.

This has been fixed in the 4.1i release of the software.
