Issue with Writer Basic

Dear developers,
we had an issue, with Basic and LibreOffice-Writer. We are a Consulting 
Company and programming solutions for other company's in germany. The 
programming Language is not relevant. It can be Perl, Java, C, ..., and 
of course LibreOffice Basic.

But first let me explain our project.

We are using the Writermodul, to generate a Dokumentation-structur. Each 
page in the document is one step in the whole projekt. We are using 
Basic to generate automaticly pages for the users. Each page is layouted 
as tables like this schematic diagram:

-------------------------------------------------
| Type  | <Description>                         |
-------------------------------------------------
| ID    | <new Item>           | <Pulldownmenu> |
-------------------------------------------------
|Content| <Text to fill>, <Graphics>,           |
|       | <another Table in this Cell>,         |
|       | <Crosslinks in this Document>,        |
|       | <Hyperlinks>, .....                   |

.....
-------------------------------------------------

So the user can describe the Project. The Content-Cell can be very big 
and sometimes scale about two or more pages. That work's fine. If the 
user save's the document, we are using Basic to check if everything is 
filled out the right way, building Bookmark-Entrys to easy access the 
pages in the document and some importend other things.

So now our issue.

To generate bookmarks, making checks, ..., we are scrolling with Basic 
through the whole document. To protect the visible scrolling and speed 
up the process of checking, we are using the Basic function 
"ThisComponent.lockControllers" and at the end of checking 
"ThisComponent.unlockControllers".
And here is the Problem. If the document grow up, let me say about 10 
and more pages, pages get lost and information in cells can't be 
checked. If we don't use "lock/unlockControllers" everything works fine, 
but it slow down the process extremly. And if the document has up to 100 
and more pages, "You know what User's say to me, ..."

So can you explain me this effect? Is it a memory problem (I'm using an 
Apple with 16 GByte of RAM and fast Core i7 CPU). Is it a Bug in the 
Software, that you havened heard about? Are there any workarounds about 
this effect?

I'm glade, if you can give me an answer.
