I would just like to point out for the newbies around here like me  

 that I had difficulties not only with IZArc failing to extract all the files for the nightly builds but also with 7zip 

 .  It's only taken me 2 days to get a 'Hello world' to compile through CodeBlocks.  I kept thinking I had bad downloads.  
Am I the only one having problems with 7zip?  
I had lots of problems with gdb in Bloodshed, so I am glad to see how well it is integrated into C::B.
Great product by the way!
