Load project issues

[richardh]

Loading a project gives "access violations" on at least some models.

Loading a project with constraints between two fit pages looks like it loads OK (apart from 5 or 6 access violations) but hitting "fit" in the constraints tab goes into an infinite calculation, with

2016-10-08 14:40:11 : Fitting is in progress…

or "fit" on an individual fit page gives errors below and then removes the fit button
