Re: help to design ui for jabber client:)

well..of course i always look first into man pages..:)

The function new_form returns NULL on error.  It sets errno according to the
function’s success:

thats in my man pages...its libncurses version 5.6+20071124-1

And im pretty sure that new_form returned null and right after that errno ==
-4...and that is E_SYSTEM_ERROR.

And as i said in last mail...really very curious workaround was to move code
at the beginning of initWindow function..that means before initialization of
second form.

just for fun i will upload my source code...i hope nobody will look at it
though...cos i guess its really ugly source code :). But if someone would be
curious :))...when line 117-147 was on line 184...cmd_form =
new_form(cmd_field); returned null..
