Since updating to the latest version (7.05a) we are now having an issue where some of the fittings are not showing on the preview. They do show when in the fittings link list pop up window and do export but not all of them are showing when in the preview. In some cases where there are features on both panels in a single fitting, such an on a hinge, the fitting is showing on one of the panels but not on the other. Again this exports fine.
It is making it quite hard to check projects for errors before cutting.
