Check and set all layers to on mode. Then inspect to make sure that there are no entities/annotations in the zoom out area. Also uncheck "Hide dangling dimensions and annotations" under Tools > Options > Document Properties > Detailing to make sure there is no hidden dangling stuff.
Finally if there are no views in that drawing, then better start a new one. If you find it is still doing same thing with the new drawing also then save your sheet format, start a new drawing with a different sheet format/size (you may use the one default from SOLIDWORKS) and then swap the sheet format. Save your drawing template and all should be fine.
Seems the only way to solve it was by starting again, copying the drawing blocks to a new file, seems to be working now,
not sure what happened, there were no dangling items, only one layer and the drawings looked to be behaving normally.
