i got strange effect, when i compile and run my simple

winapi program sometimes (recently often though not all the

time) some strange border appears around my app window

it is working a couple of seconds then closes silently)

I got no idea what it is

(this border is red, though i was tinkering with customization

of windows so maybe i set this color, though normal elements

ale not red here, so i dont know, I am using winXp sp3)

Can you show us a minimal code sample that exhibits the problem, and perhaps a screenshot showing exactly what the visual effect you're seeing looks like?

Are you doing anything unusual (like this experiment of yours) in the problematic code, or is it a normal program other than the error in question?

this was probably avast shield thing, what a hellish thing (i could find it in my source till the end of the world),

i compile with -s -fno-rtti -fno-exceptions and got really smal exe

(raytracer of size 14 kb exe) it was probably something the avast

didnt like :/
