It is with great embarrassment that I offer my apologies to the 2135
people who downloaded Mosaic 2.3 before I withdrew it. In my rush to
get out a version that fixed the telnet URL security problem, I left in
an ugly flaw that caused Widget names to appear to the right of all
toggle buttons in all forms. I'm very sorry for all the inconvenience
this may have caused. I am now releasing Mosaic 2.4, which is identical
to 2.3 with the exception of fixing that one foolish oversight.
