New to Solidworks. Have done the tutorials.

Did a new part and I am not able to double click dimensions in the drawing sheet to get a 'modify dimension' box to open. i.e. the Dimension window opens up to the left side of the screen and when I open the properties window it shows the dimension as 'Read only'.

Also a second problem. When trying to produce a Section view, it doesn't see a hole and orb port???? If I delete the section view, and try again to do a section view of a different view, the view name advances and still does not show the hole or orb port. eg. says the previous name was M-M then the new section is N-N although M-M doesn't even exist????
Have resaved the part and the drawing and even rebooted Solidworks (2006)

Thks,
