Anyway, when I click on "view target/source preview", it just says "please wait" for a long time, then says that Powerpoint is not working, then an error message "tries: 10. max: 10" (i.e. it has tried 10 times to open Powerpoint and failed), then it does show a "preview" but all that preview is is a completely blank document with nothing on it, just a white screen. Then when you close the preview, the entire Across program closes down without warning or saving.
I don't use Across but it can be a result of the macro security level in PowerPoint. Lowering it may help.
