Win XP Pro, Service Pack 3

For last week or so my clipboard taskbar is not clearing after pasting, and sometimes shows 2 instances of itself in taskbar
And when clear the popup shows items collected (ie ‘Ie ‘2 of24-clipboard item collected).
(The only change I have recently made is installing “VoiceZone Connect” from Time Warner Cable which shows who is calling on the telephone)

Any suggestions? My thanks
