I did see one post where this was fixed "cough"
Only problem was the guy had to reformat his drive after he got a virus and after he did a re-install of windows his issue with long shutdown with swtor was fixed.
I'm more inclined at looking at why windows is having an issue closing the program, which is why I asked if it behaves the same in fullscreen window mode.
(not saying a virus caused it just after he did the above it was fixed for him)
I blame my higher electricity bill on memory leaks as well
