[TYPO3] Problems with CATMENU in tt_news

[Michael H.E. Roth]

Hi,

somehow I cannot get it to work :-(

I cannot get to see only the news of a selected category out of the 
category menu :-((

I set up the following News-Categorystructure:

base
-level1 item1
--level2 item11
---level3 item111
---level3 item112
---level3 item113
---level3 item114
--level2 item12
---level3 item121
---level3 item122
---level3 item123
---level3 item124
and so on

2 level1 items with each 4 level2 items which in turn have 4 level3 items.

Now I defined these catategories in a sysfolder which is also the 
generalPID for the website root-page.
The next thing is that I created a sysfolder structure under this 
"base-sysfolder" representing exactly the categories so I can put the 
news into the corresponding folder.

Now I set up a page (currently not in the menu but otherwise visible) 
and put the new-extension as the only content element.

General-Settings Tab:

What to display: LATEST and CATMENU
Order by: Date/Time
Sortorder: Descending
Category mode: Show items with selected categories
Category selection: base
Archive setting: don't care
Startingpoint: "base-sysfolder"
Recursive: Infinite

Template-Tab and Category Settings Tab:

All fields left empty except:
Category Image Link Mode: Acts as a category selector
Category Text Link Mode: Acts as a category selector

Other settings Tab:
Page Id for single news display: the page with the single view tt_news 
content element

TypoScript Settings:

plugin.tt_news {
     useSubCategories = 1
     displaySubCategories = 1
     categoryMode = 1

     displayCatMenu {
         catmenuRootIconFile = EXT:tt_news/res/tt_news_cat.gif
         catmenuNoRootIcon = 0
         catmenuIconMode = 1
     }
}

I also set up another page structure, which again represents the 
category structure, under the news-page and assigned each category the 
corresponding page as the shortcut.

But whatever category I click in the category-menu I always see all news 
:-(((

What am I doing wrong???

TIA for all hints and tips

Michael
