Black window or runtime error

[pozsarzs]

Hi!

I am not a Windows user. I must converted a Linux application to Windows.
I built it without -WG switch (Win32 Gui app.) and I probed run.  It is OK.
After it, I built with -WG switch. It compiled succesfully, but it gave an error message and stopped when I probed to run. What is the error?

Thank, pozsarzs

(And sorry my bad english.)

If you compile with -WG, you can not write any text to the console.
The current CVS version of lazarus is OK, in this respect: it does not write any text (i.e. writeln('Some debugging info')) to the console.
