I don't know the reason, I have heard this may be the cadence's bug ,
but how to solve this problem? Some one has said "out it and recopy it
on" , but I want to find a more efficient way because capture only
reports one error like above every time.
SO, please help me . Any effort from you will be grateful.

Best regards.
