There is macro variable that sets that behavior:
def_paste_block_cursor_end
You probably had it set to 1 in a previous version and it didn't migrate.
The settings for block paste available are:
0 - (default) no movement
1 - cursor below pasted block (orig column)
2 - cursor on last line and last column of pasted block
3 - works like 1 except at end of file. At end of file, cursor is last line of block, orig column (doesn't insert blank line).
That should really be in the options somewhere, I file a request to have that done.
