working in Libre Office 4.3 Impress, on a large presentation, the system crashes with 'Bad allocation 'report when trying to save. Is there a cure? Mark

Presentation is about 170MB with many images

System crashes? Btw: what system?

If you use Windows, then 4.3 is definitely 32-bit. You may want to change to 64-bit (and a little more fresh, like 5.4).
