[fpc-pascal] Installing on Mac OS X

[Paul]

I removed all files (that I could find) and reinstalled fpc-fpcsrc-lazarus.
I downloaded the files from www.hu.freepascal.org/lazarus
According to the docs in 
http://wiki.lazarus.freepascal.org/OS_X_Programming_Tips, I should now be 
able to start lazarus by clicking on the lazarus icon in the application 
folder.
I can't fond it though, also not with spotlight.
Where can I find this ?

OT: is it normal that new windows are hidden behind others?
When downloading the packages from this site (very slow), I was under the 
impression that nothing happened at all: the progress window is always 
hidden.
The same with starting a new instance of Finder: click and search to find 
the new instance under other windows.
