Is there any advantage of using the portable version of Screenshot Capture vs. the regular version, other than portability. Does the portable keep my system less prone to problems

Thanks very much, I'll give it a try.

That would be great if it were an option. I'm mouse-centric and I've been looking high and low for a clipboard manager that I can easily access with a mouse from the task bar or system tray. So far the only one I could find is Clip Mate, I like CHS features and ease of use better though.
