Hi all, I had this problem report from a customer yesterday:
I opened the large 115 slide vsdx file, and I started thinking that the two main symptoms ( 1) exiting F5 presentation mode when pressing down arrow to a page that has not yet been displayed in presentation mode, and 2) crashing out of Visio entirely when doing a find) both felt to me like the full file had not yet been loaded into memory. One time, when I opened the file, it was on slide 111/115. So, I used Ctrl+PageUp to scroll (and load into memory) up to page 1. I then pressed F5 and then down arrow repeatedly. F5 mode worked fine. Interestingly, when I got to page 112, it exited presentation mode and went back into design mode. I then used Ctrl+PageDown to get to page 115. I then entered F5 mode again and up arrowed to page 1 and down arrowed to slide 115 successfully. Loading the entire file into memory seems to have fixed the problem. And, I could also then execute a Find (30 hits in 115 slides and then wrapping around to the start of the file to see hit 1 again) successfully.
Very strange. I have never encountered this sort of problem, but I have also never built a Visio file this large.
I am still in a bit of disbelief that the problem went away, at least for now. I was steeling myself for a very ugly file reconstruction task. Fingers crossed.
