Vince is correct, this is a bug in Tcl. It only shows up under Windows
and it is easy to work around (just set your CLASSPATH var to something).
Can we avoid any more posts about this issue? This list is for Tcl + Java
related issues. Tcl bugs should be discussed on comp.lang.tcl, not here.
There is already a thread titled "[Bug Tcl 8.2] setting env variable array
is broken under Windows." on comp.lang.tcl and a bug report has been sent
to the Scriptics bug database.
