OK. I try use JEDI header (this header have dwStartDelay option in DIEFFECT structor.

2) manually define "DIRECTINPUT_VERSION_6" conditional (in project options dlg).
I will try to do. :roll:

Or just use updated headers from CVS: http://cvs.sourceforge.net/viewcvs.p...dx9sdk/Headers .
I download new header from http://clootie.narod.ru/delphi/download_dx92.html in last night. Are there same header?
