Crowded P&IDs Cause AVEVA Diagrams to HANG

Hi,

Has anyone had experience working on crowded P&IDs in AVEVA Diagrams 14.1.3?

For very crowded P&IDs, AVEVA Diagrams would Hang, FREEZE and working on P&IDs will become very time consuming.

For example adding/deleting a TEE on a branch may take 30 minutes!! and sometimes Program will remain in "Not Responding" Status and user should END TASK the Diagrams.

Regards
