found out what was wrong with my screen-shot this code solves the problem

Code: Select all

db 0
:)

I was testing words not bytes so my lodsw grabed my 0 at the end of the line and then some untill it started printing the idt, it probably stopped at the offset[16-31] part of the first desctriptor because I'm still working in the real mode memory range. I feel better now but just a bit silly.

Not exactly a screenshot but rather a commit message.

I unintentionally wrote:
"did some cleaning. broke arm."

Thats why I never vacuum =)

That's pretty funny :-). I hope you can still program with the broken arm...

The cause:
- Add alpha blending support for the mouse
- Regenerate all textures in ARGB format. Forget to do the user background (because it's in a different folder).
- Not clear the backbuffer when switching users (as they all have an opaque background)
- Draw those opaque backgrounds with transparency aware code.
- Login as that user.

Bitmaps are actually stored the wrong way around :wink:

Me? :twisted:

Consider this: did you ever find a case where you could load a bitmap and use it as-is, without flipping it upside down in software (that also means not using API calls as they do it as well)
