(1) clipboard dialog box > options

(a) "show office clipboard automatically" is selected, but nothing seems to happen if I select & copy text (or have I misunderstood what that means?)

(b) what does "show...when Ctrl + C pressed twice" mean - it doesn't seem to work

(2) I have "keep source formatting" selected as the default but

(a) when I paste a word by clicking on it in the clipboard it pastes with all the formatting but the font reverts to Times New Roman, though this doesn't happen if i paste by using Ctrl+V or the paste button

(b) this also doesn't happen if a whole sentence including the full stop/period is copied & pasted

Does anyone have any idea what's going on here & how to make it work correctly?

TIA
