Hello Sudip,
yes. We face the same problem with Creo 2.0 M070 and Windchill 9.1 M070.
We have been struggling with this since January 2014 but we didn't find a solution. PTC Support was'nt very helpfull either. They recommended to try out a higher maintenance release oF Creo.
I would also be grateful for a decent solution.
Best regards
Johannes
