Tooltips all have "cntl-P" added to them with JDK-1.2fcs-C on both Solaris and Windows NT. I noticed this with both SwingSet and the JCK suite, so its not just SwingSet doing it.

Steps to Reproduce:
0) Launch SwingSet with the configuration above.
1) Go to the Tooltips pane and point to the cow until a Tooltip appears.
RESULT: It has the usual message in the tooltip plus a little "cntl-p" added on the right end of the tooltip.
