The new Release 20.03 is out! You can download binaries for Windows and many major Linux distros here .
I installed * svn build rev 7041 (2011-03-06 11:42:54) gcc 4.4.5 Windows/unicode - 32 bit Is that a reasonably recent version?
Is there a non-unicode version?
Does cb have a "gui designer"? If so how do I get it going?
