[1.6.4] Fluids a cind of...strange

[TechoMan]

I'm back...Its my second atempt of creating liquid.Now i'm having new problem - fluid dont want to flow at all....or actyallu it will flow , but in very strange method. When placed , they are only 1 "pixel thik" , but i even used setQuantaPerBlock to 12, but it still only 1 thick...wich is very strange ( http://snag.gy/6NMpm.jpg <= screnshot of it , idk how to attach screnshot to post , so i'm using snag.gy ).Next - its cind of realistic how it works , but i dont want that. When they fall on top of themself....they like in real - stacking into bigger liquid.They even flow then , but its like in real life.I dont think MC players will like that , so why does it happen?

 

And second question - how i can apply effects when player in liquid? Like lava makes you in fire.
