just finished installing my host and thin client but want to use OpenbravoPOS on both my pc's at the same time what can i do???

tried alot of options but seem to head in  the same direction.........

if you open the program on host pc it doesnt want to open on client.please advise cause i am new at this????

Sound like the java app is one user per machine per instance. I had an app like that, that is what lead me to using Virtual machines.
Did you contact Openbravo suppor?. Can other programs open, i.e. Internet Explorer, Word etc to rule out the the thin client being the problem. Remember not all programs are written for multi-user environments.
