Dear Hackers I have installed ptolemy 0.7.1 on my RedHat 5.2 machine. I ported my work which was done on ptolemy 0.6 under Slackware with kernel 2.0.0 in my work I have 2 types of messages MUpacket and MSSpacket. on the first run of the simulation everything is going very well. if the simulation ends and I try to run it again. I receive an error by some stars that they received the wrong type of message for example the star which suppose to receive MSSpacket receives MUpacket. if I close ptolemy and run it again and then run my work ... everything is going well. any suggestion would be appreciated.
