when running tabcmd from a windows command line, if there's lots of messages, then the top ones will be cutoff. You can solve this by redirecting the messages by using the greater than sign.
tabcmd xxx > location_of_where_you_want_to_save_log_file (e.g. g:\tabcmd_test.log)
Even the log file doesn’t contains all errors. It is capturing the error that are getting display on the screen.
the logging is built in windows functionality and it should show all the messages.

>> appends to whatever is there.
do you have enough disk space?
