Let's see, Mikl__. What you are doing is ripping my codes and posting the resulting codes here. What is the effort? I asked you to help me on continue working with the Desktop Window Manager, because I don't have enough time, but you omised it and working on what you want (nothig to say, you can do whatever you want). But, tell me where is the effort? doing what I have already done?

[Mikl__]

Hola, Alonso! En cuanto a la Desktop Window Manager escucho por primera vez, me tienes con alguien confundido. Conmigo usted habló de la AOW32 traducción al ruso

[avcaballero]

I did, it was in our mails. Are you translating it to russian? Where you are working on is in AOWG, not in AOW32. AOWG has all the libraries available to download for all the examples, it is just that I had no time to make everything also in asm, that is what is missed, everything was coded in c, you can compile everything. This last fern is from AOE in MS-DOS. Nevertheless, you can keep doing what you want.

Hello, I have reopened AOW32. There are a lot of new things, but it is heavily in progress, so many things still missing. Almost everything is in Spanish, the English part is quite outdated. Though it is in asm and c, TinyC is the central and many asm versions are still missing, until I have time to complete it.
