ipcskillprocess control

I am using ipcSkillProcess to extract Cadence schematic information. I am sending a command to a skill procedure from perl and seems to be working fine.

lcid = ipcSkillProcess("DisplaySchematicTree")

while(ipcIsActiveProcess(lcid)

;based on the input i get perform an operation perform an operation here

)

This seems to be working fine. But  the ipc process(in this case "DisplaySchematicTree" controls the virtuoso session and i cannot peform any operations on my Cadence database.

Can somebody share there experience on how to solve this issue.

Thanks
