Top Menus Question

Hi, folks,

I'm in the process of moving my web site to WP, and have installed WP 3.01/Atahualpa 3.5.3, on SuSE Linux 10.2/ISPConfig 2.

There are 2 menu groups supported by this theme, atop of graphic header image (still default) - categories/pages, and below it - categories/posts. So far I have defined only "Menu 1" to display "Categories".

Here are small problems I've got.

1) On top menu #1 categories/pages are displayed even if no pages are defined under particular category.

2) Menu title itself is "clickable" with link followed by message "Sorry, but you are looking for something that isn't here.". However, my idea was to display and click menu items, not menu title.

3) Menu #2 IS displayed despite the fact it is not defined in WP -> Settings -> Menus. "General -> Posts" on blue background on screenshot.

4) Render of "Pages" content is fast - 0.1 sec in average. However, rendering of "Posts" is whopping 26 sec! I think it is not related to theme but to some glitch in setup or whatever else. Anyway, may be someone know what could be the cause.

Please look at screenshot attached.

Thanks in advance for any suggestion(s)!
