hi,
when softice reached 40289F and i press f10(p) softice jumps but i dont see where it jumps to.
when i tried to find 4028A2(in SI) i only find 4028A1 with a stange adress(like 3245:35765554).
After typin f10 few times i finaly see the highlighted line again, but i dont know what is exclusiveOred[] and i really tried to find it. Is it a softice error?

It's not an error on Si's part, it's a protection approach: You jump to the middle of an opcode. Softice will disasm the code opcode by opcode, instead of looking at the code flow. If, in si, you press . and then return, si will jump to the current eip. Thus, it's just a trick, to make you debug some code, that you would rather jump over, or run it before you get a chance to see it.
