This may be a result of using Enable auto recording from the
Options/Recording Options... window. Captivate captures screens via
event triggers. In other words, click the mouse and snap a
picture...press a button and snap a picture, etc. The issue that
often arises is that the capture process is quicker than the screen
render so you start to see oddities like those you describe. If you
are hearing the camera click sound before the screen fully renders,
then this more than likely what is happening.
I use two options to counter this.
1. Turn off Enable auto recording and go the manual route by
click Print Screen when you want a screen shot. The disadvantage of
this is that you have to manually enter all the functionality,
captions, etc. rather than having Captivate help. The advantage is
that you have a great deal more control over the capture process.
2. Another method is to continue using auto recording, but to
make liberal use of the Print Screen key to capture additional
screens as you go. For example, click on an icon and Captivate
takes a screen capture....now click Print Screen to take an extra
screen after you are the screen has fully rendered. Just be sure
not to move your mouse before taking the extra screen shot. In the
Edit environment, you can simply delete any extra screens that you
find you don't need.
