- UPDATES
-
-
-
- 1.0 Initial release of PWPLUS, a much improved version of
- the PW password program.
-
- 1.1 Color change menu added. Improved error handling
- procedures. Bugfix - as a result of changing from PW's
- COM file format to EXE, the system lockup after a failed
- entry attempt was the result of a program lockup rather
- than a controlled keyboard lock.
-
- 1.2 Enhanced keyboard rate for editing, logfile viewing.
- Improved critical error handling further, should be
- pretty much bombproof now. Improved upon all
- procedures, and tightened code.
