First of all, I'd like to thanks Mr. Dale Harris soooo much for making a really great POS software, for FREE!

Anyway, I found this software a couple of weeks ago by googling the words 'point of sale software'. I searched for a POS software because my older brother was about to open a small Japanese restaurant in my town in Pontianak, Indonesia.
He already has a programmer to make a cashier program for him, but the programmer just didn't show up at all! So, he got confused to where else to look for a program, so he asked me to search it in the internet, and I found this really cool DHPOS software!

So, I started to set it all up for his small restaurant, and it works great. However, there are times when we're about to close the register, the software just freezed. So it's likely that the program didn't really close the register. Then the next day when we open the register again, all transactions just added to the previous day transactions. So we got all confused, and we have to track and note down the transaction one by one from the Void menu.
I wonder what's wrong with it? Is it because the data gets too big that it affects the program somehow? But the restaurant just started a week ago. Please help. Thanks a lot.
