I did a simple test with the CRC32 object. I created a simple program that would get the CRC of a file.
The program just consists of a button, an Editbox, the File object and the CRC32 object. When a user clicks on the button it opens the load selector dialog from the file. Then it does a text CRC via the CRC32 object. It gets the file to check from the Get Result Pathname expression.
I have a couple other programs that are able to get the CRC of a file. The two other programs get the same CRC whereas when I use the program I created with the CRC32 object I don't get the same value.
