Menu doesn't display with framebuffer

[dgc]

Hi —

I'm new to iPXE. I really like it, but I'm having trouble with aesthetic parity to our pxelinux installation. I have a menu that works fine in VESA/BIOS console(?). But after I try to use the "console" command to configure the framebuffer console, "choose" does not display the menu. I can keyboard around and select something by counting keystrokes, and the correct result goes into the choose variable, but at no point does the screen change.

Working test case:

Code:

console
menu foo
item bar
choose baz
[menu displays; I press enter]
echo ${baz}
bar

Non-working test case:

Code:

console -x 800 -y 600
menu foo
item bar
choose baz
[cursor sits still and no menu displays; I press enter]
echo ${baz}
bar

Any ideas what this is? Did I miss something in the docs, or is there a known issue?
