While adjusting contents with sledit I click edit (editing: cash register). The MAX edits perfectly, while trying to change the MIN it clicks then miss clicks ? like it highlights the MIN amount then unselects it. If I'm fast enough I can change one digit but Im trying to switch it to 300 and I can only type 3. its like its trying to click on the menu below it... it flickers and the icons for the items turn to black and blue/black and grey.
