At long last an update (or CSD) for Ultimail Lite has been released. This is the first widely available update since April '95. It will update Ultimail to v2.10.003. It fixes many of the known bugs and speeds up certain operations. Large folders no longer take forever to open, and the mail cabinet shuts down in a reasonable amount of time. Also noticeable is a fix to the problem of Ultimail inserting extra blank lines in your text.
Officially it is a "beta" CSD, but I highly recommend you apply it, even if you are not currently experiencing any problems. It will probably be available by Retrieve Software Updates soon; but in the meantime, it is available by anonymous FTP. The file name is umf21003.zip and is currently available at testcase.software.ibm.com It may be moved from this site when it becomes official.
To apply the fix, unzip the downloaded file then run install.cmd Do not unzip the files within umf21003.zip and do not run TCPINST.EXE, use the cmd file which will run it for you.
