Window position altered by completion

[smutch]

When completing the name of a C struct member, the line currently being edited is moved to the bottom of the window.

i.e. If I have a struct called foo with a member called mbr and try to complete:

foo.m

then the window is scrolled. I have confirmed that setting completeopt-=preview makes no difference.

My neocomplcache options are below:

" Disable AutoComplPop.
let g:acp_enableAtStartup = 0
" Use neocomplcache
let g:neocomplcache_enable_at_startup = 1
" Use smartcase.
let g:neocomplcache_enable_smart_case = 1
" Don't use camel case completion
let g:neocomplcache_enable_camel_case_completion = 0
" Don't use underbar completion
let g:neocomplcache_enable_underbar_completion = 0
" Set minimum syntax keyword length.
let g:neocomplcache_min_syntax_length = 3
let g:neocomplcache_lock_buffer_name_pattern = '\*ku\*'

" Define keyword.
if !exists('g:neocomplcache_keyword_patterns')
  let g:neocomplcache_keyword_patterns = {}
endif
let g:neocomplcache_keyword_patterns['default'] = '\h\w*'

Can you explain the behavior by screenshot?

[smutch]

Here is a quick example. Here the current line hasn't been scrolled to the bottom of the window, but has moved by several lines...

This occurs also for 500+ line files viewed in full screen mode on MacVim.

OK. I improved neocomplcache for it. Please update.

[smutch]

Fantastic! Seems to work great. Thanks so much for the rapid response!
