copy&paste

HI,I have run into problem when it comes deleting previous copy&paste in emails already sent that is when i do another copy&paste the previous one comes up instead,thank's

What are you using for the E-Mail Client? The Windows Clipboard can hold only one item at a time, clears that one out when doing another Copy or PrntScrn function. Turning off or rebooting the computer clears the RAM/Random Access Memory which removes anything in the Windows Clipboard.
This is for the Windows version:

Don't know which version of Office or Outlook you are using, each is different from each other. Some versions of Microsoft Office can hold more items, it's a separate clipboard from the Windows version.

HI,Berton,I do not have clipboard on my PC it is gone.
I use COMCAST email to send emails and use FIREFOX most of the time if not all of the time my understanding is clipboard was removed from WIN 7 is this right as i have been looking for it and so far have not it.

Clipboard is part of Windows and still exists on the latest versions. Copying to the Clipboard makes the item available to Paste into a chosen program, e.g. MSPaint. Test it by pressing the PrtScn key then open Paint, in Start, Accessories, click the Paste icon or Edit, Paste to see what you get.

Well i went and did what you suggested and it worked,but i still do not know why i got previous emails coming up before i was able to send the next one being M/S is just another one of their quirks.
