yep, atm, ddbg ignores all breakpoints that it didn't set itself.
i'll take care of the int3-issue for the next relase.
until then, you can use the OutputDebugString interface to simulate a 
manual int 3:

OutputDebugStringA(toStringz("Ddbg: bp 
"~__FILE__~":"~.toString(__LINE__+1)~"; r"));

if you wrap this nicely, it's similarly convenient.

didn't sound angry me. besides that, feel free to be angry. it helps to 
improve things ;)
