Forget my last post...
To test I changed the test i speak about from
if ((_lastAppliedProgramObject!=0) &&
(previousLastAppliedProgramObject==_lastAppliedProgramObject) &&
_defineMap.changed)
to
if ((_lastAppliedProgramObject!=0) &&
(previousLastAppliedProgramObject!=_lastAppliedProgramObject) &&
_defineMap.changed)
And it seams to solve the problem (no more unecessary useprogram)...It don't
seams to break the stuff but I'm not sure
