console window problem

[Hartmut Birr]

Hi,

I've problems to start cmd.exe in gui mode. I get a very large (height) 
console window where the previous background is visible. The debug print 
shows this:

...
(objects/bitmaps.c:454) got bad width 560 or height 421075580, please 
look for reason
...

I rolled back my change to text.c in CVS since it seems to be the cause of
this. Not that I understand it, console windows still worked correct for me.
Staring at the code didn't help either.

Hi,

it seems that GetTextMetricsW doesn't work correctly. The value 
tmExternalLeading (guiconsole.c line 114) is set to 0xcdcdcdcd.

Clearly indicating it's only allocated, never initialized or assigned.

May I once again take the opportunity to pitch in "assert is your friend"?
