I have discovered that deleting library items decreases
project file size so Captivate won't freeze or lock up. My project
(.cp) appeared to be 266 MB with only 5 slides!!!! I deleted unused
files from the Library, which brought it down to 15 MB. Before
that, Captivate kept freezing or locking up. It was really
frustrating because I thought I had too many programs running at
the same time (Microsoft Office, the application I was trying to
capture, and Snag-It. To delete unused files: while viewing a
slide, click View/Show Library. Drag the left vertical border of
the Library window to the left so you can see the column headings.
Sort by the Use Count heading. Delete files marked "0" (unless you
really need them).
As opposed to making certain you only select files marked
with a use count of 0, why not let Captivate do the work? Just
right-click any item in the Library panel and "Select Unused
Items". Same action, fewer steps.
