Hi there community, I have been having random error problem mostly during saving, which makes me loose any changes up to last autosave.

I am using DS Professional 2017 SP1, It seems the issue only happens when using a PDF underlay but not always, every time I notice and by now know its gone bonkers again because when applying a dimension to something the dimension doesn't show, it is there if I turn the pdf layer off but won't show if on.

I wonder if it is something to do with memory? using 8GB on a Dell with i5-4460 3.20GHz, and Geforce GT705, which is also something I would like to upgrade, any opinions?

Cheers
