macOS nsmatrix2

[medasmx]

This is a rewrite from my previous nsmatrix post. I included all the code. There are two matrices (embedded in customviews). One is 1x3. In the first textfield (of the first matrix) you input a string. In the next two textfields, you state where in the second textfield matrix you want to put the string (this is a 2x2 matrix of textfields). To make the matrices I embedded textfields in custom view windows. There is one button that inputs from the first matrix. It compiles without errors, but then I get the message -- "asmcustomview[15725:10b] Unknown class NSmatrix in Interface Builder file." That happens when it loads before anything is inputted. When the button is pushed, I get the message -- "asmcustomview[15725:10b] *** -[NSTextField copyWithZone:]: unrecognized selector sent to instance 0x133ed0." Below is the code. Thank you in advance for any help. Adam
