Is Something Wrong with My Installation?

I'm using Sonar X3 Studio and purchased it (or, technically, upgraded to it) less than three years ago.  I have been away from using it for a while but am perplexed by what is going on now, as I don't remember ever having the kinds of problems I'm currently experiencing.  As an example, in Staff View, I try to copy something (MIDI) by selecting it and either pressing Ctrl + C or "edit/copy". Then I try to "paste special" to another track using either Ctrl+Alt+V or "edit/paste special".  I don't get a dialog box like I used to, asking what track to start with.  Nothing happens.  The data is not pasted.  But in "Edit/History" it shows a paste function performed.
 
In another example, I have an instrument defined, valid banks and patches selected (all showing up in the track view correctly) but the instrument will not play.  It's a Korg Kronos 88.  If the same track is routed to a Roland XV-5050, it works.  I don't think it's problem with the Korg.
 
In a third example, I tried to quantize a group of notes to some rather short duration (80 ticks when a quarter note = 960) using the "alter start times and durations" option and it would not work.  I was trying to to simulate a piano tremolo with alternating octaves and ended up entering individual notes and manually changing the starting time and length of each one.  It took about an hour to get 1-1/2 measures done.
 
As I said, I do not remember Sonar being so "difficult" and I suspect there is something wrong with my installation.  How would I be able to tell if that's the case?  I am in a situation where I have to get productive fast and this is grinding my progress to a crawl.
