[Elecraft] K3/P3-SVGA: Problems with ending Xmtn of stored messages

[RICHARD SCHMIEDT]

Equipment: K3, P3 with SVGA board and TX Monitor.  All firmware up to date.
I use the P3/SVGA memories for sending my canned messages in digital modes, typically in RTTY using FSK.  I'm having problems with ending the strings being transmitted either by hitting the ESC key or by using "|" at the end of the text string in the memory.  
Often if I hit the ESC key to stop xmtn of the memory string, it will flash END in the K3 text window, the K3 will go to rx, but then it go back and start Xmitg the remaining part of the string.  I often have to hit the ESC key two or three times to get it to finally stop, or just wait for the diddling to finish.
The opposite is true if I use the "|" at the end of a memory string to stop xmitn.  As the string memory is flushed to the K3, as soon as the "|" is flushed, the K3 text window reads END and it stops the xmitn, so only about 3 characters of the message actually get xmitd.  If I take the "|" out, the full string is transmitted.
These events seem to be somewhat random.  Sometimes the ESC key works perfectly and other times it doesn't.  Same with the "|" problem in the string.
It its not an RF problem, because it does the same thing in the test mode.
Any help would be appreciated,Rick W4GE
