HI Guys, here is some update and further questions - i'd say it is some magic here...

well, as i couldnt find the solution and no one responded, i gave up and started adjust the website... i paste some piece of code in the header in left sidebar section so i have the JS slideshow looking like the book with moving pages.. since it didn't work out and the whole page layaut has been messed up i carefully deleted this code and here it is... my previous problem dissapeared (there is no longer empty space above the header) but i lost the horizontal lines that should be between every posts.. now posts are displayed one just after another without any 'deviders' between them...
so i reinstall everything: a wholl wordpress, database, athalupa theme... well still nothing... now i have the page just in the place i want it, but with bad layaut..
so question is how to add the horizontal lines that should be between posts??
thanks a lot!!! stan
