powerpoint crashing

[Chris Burton]

Hi everyone

Im presently having a real problem with powerpoint crashing after I 
open a previous presentation I have done, and selecting to show all 
slides as thumbnails on the screen. Has anyone had this occur? I need 
to fix it as I have a presentation to do early tomorrow and they want 
it on their PC system, so I cant show off Keynote.

I have downloaded the recent Office X update 10.1.6 but, the problem  
still occurs

many thanks for any advice

kind regards
