yes, it seems there are 2 issues here

still confirming it

let me partially retract this statement...
after more accurate test I found that even a "virgin" 3.5.0  has a slight  
when start typing... just 2-3 seconds...

try typing "test" and hitting space... you will see that the cursor  
freezes after "tes"
then writes the last letter and the space...
with any word you use, there's always this 2-3 seconds freeze after the  
3rd letter...

it seems that huge autocorrect databases create a second freeze

try this: enter the autocorr subfolder in your user profile (in Windows is  
under: User\LibreOffice 3\user\autocorr)
and put the attached acor_.dat file (backup yours first) which has 64000  
entries inside it.

start LibO and open a blank writer file.
digit "test" and hit space...

you will see a first 2-3 second freeze after "tes" the the cursor moves to  
and another longer freeze (6 seconds maybe) happens before you see the  

so there are 2 freeze moments, the first one is shorter and unrelated to  
while the second is longer and depends on autocorrection

these tests were done on LibO 3.5.0
Windows Vista 64bit SP1
