Thanks for the reply. I waited to have some specific questions to ask.
Occasionally when entering a coin I get an error message, "Cannot open any more tables.". And, sometimes the message reappears repeatedly after I click the "OK" button. The only solution I've found it to exit the program and restart. In the later case, exiting has to be done through Task Manager/End Task route, which has me worried about possible database corruption.
1/14/2023 Just got a new error. "Object invalid or no longer set." This happened when I clicked the Add Coin button. I clicked the OK button on the error and it was replaced by "Cannot open any more tables." Restart program needed.
Your YouTube videos have answered a number of questions and I haven't gone through them all yet.
