it results in an error. The cause was a bad library
upgrade and has been solved on CVS for a month now.
EmSim 2.0 won't present this bug.
This is only a graphical bug because the sink symbol
doesn't play any role in simulations. Replacing the
sink by no symbol (an uncaonnected edge) is equivalent.
If you really need the sink symbol for graphical
purposes, then you can copy/paste it from an example
were it's present or even add it in the xml (.jgx) file
by hand with a text editor.
Tip: when such graphical bugs occur, you may still save
your work by choosing to close EmSim. Then it will ask
if you want to save your file, simply answer yes. Regards,
