Yes, it was under Windows, compiled with Qt Creator 2009.02 (Qt version
4.5.1), with the default build options. I just unpacked the
kst-2.0.0beta3 archive, opened kst.pro in Creator and clicked on "Build
all". The resulting exe is 43 MB (!) so yes, I suppose it is a debug
build :-)
I don't know how far your son has come with preparing a Windows package,
but one thing is sure: he'll have to change the build options. And one
thing I haven't tried is to compile gsl under Windows so that we can
have all the nice plugins based on it. It would be nice to do it...

Thanks for your support,
