Hi

I am running SW2012 SP5 and I am having problems with the dimension input box disappering.

Sometimes when I come to dimension a sketch element I click on the dimension tool, click the element and the dimension is placed without me being asked to change it (i.e. the input box not appearing).  Sometimes the input box comes up the first time i select an elemnt and then not again, sometimes never.  I have check that the "input dimension value" check box is ticked in the general options.

can anyone help me with this?

Thanks

Ben
