The software already keeps track of hands of all the hands it has saved and will not rewrite the hand history if the hand number has already been recorded. If you are recording thousands of hands without ever closing the program, it will take longer to check the match list as it is now thousands of hands long.
Once I finish getting the last few kinks out of the open/close table function, and get that out the door, I can go back and add something that will speed up the check for hands that are already recorded.

If you use the Force Scan button the software will go to the first hand of the Hand History window and check all the hands on the list. When the timer fires it will start from the present selected hand and then scan to the bottom of the list. I had the default timer as every two minutes, but have been using 30 or 45 seconds to keep the table information up-to-date for closing tables.
