Why is Xilinx's WebPACK so inferior?

There is no particular need for improvements but there is a
big need to fix it.  The schematic flow is totally broken
in versions 8.1, 8.2 and 9.1.  8.1 would not import a version
7 project.  8.2 had such a bad memory leak that it would not
make it through xst.  9.1 showed no improvement. Your support
people sent a fix for part of the memory leak but that showed
two more fatal bugs.  The ucf file pin assignments get used on
submodules and so it thinks there is an error and, if you remove
the ucf file to try to go on, it cannot find the libraries and
quits. It does however, destroy the project file in the process.

I plan on converting these to vhdl but it would be nice to be
able to do it in an incremental manner.
