Annotations showing after....

Particularly in an assembly all the annotations show afteradding a hole esp. tapped.
There are no dims etc. showing prior to adding the hole. I can turnit off again but it brings the system to a griding halt while isshows the annotations.

Is there a way to stop SW automatically showing all the dimensions?
e.g. is there some special set up in the annotation display that Ishould follow?SolidworksUser Interface
