Exploded and stretched dimensions when reopening drawing

Hi, I hope someone can help me with this issue, I'm working with SW 2011

I'm working on a detail drawing, then I save the file. When I reopen it, a lot of dimensions (not all of them) appear with 10x their size, with incorrect positioning, and it's becoming a real issue because I cannot do anything about it. If I start the drawing again, it happens at some point, and I don't know what am I doing that's triggering this. The first picture is a quickview of the drawing as it was first saved, the second one is when I reopen the drawing.

Thanks for your help
