Showaco 5.1 programs tab seemed to be 4 wide. 5.2 is 3.
I did notice sometime when running 5.1 that it would switch back to 3 wide but I would scroll off ..then back on and it would be 4 wide. 5.2 seems to be 3 wide always.
Update: if u reinstall the 2 files I commented on page 319 that fix the programs tab, you can go back to 4 programs per row after having updated to showaco 5.2
