Hi Robin
I'm not familiar with CAP 2.23, but I will mention a screen capture utility I have used for years.
It is Hypersnap Pro which as well as being able to capture many different parts/types of screens (including optionally being able to capture cursors) it performs many functions (crop, resize, resample) that I have found useful in the 10+ years I've used it.
You can download a trial copy from

PS -- they also have HyperCam, which is powerful video capture software that records AVI movies (screencam) directly from your monitor, for software presentations, software training, demos, tutorials. This might just interest some recent posters. I've not used this application.
Update: After writing the above, I downloaded HyCam and managed to make a flawless screen video without even reading the help files. I've since gone back and purchased a copy.
