Re: [ROOT] Unable to call methods in GUI constructor!

Hi Christian and Fons,

I just tried it and Christian's script doesn't work neither on MacOSX
However, if I replace the line 321 :

this->Test(1);

simply by

Test(1)

which is usual, everything works fine. So maybe there is an interpreter
issue here, which is not limited to GUI. But I'm not able to investigate
more. Hope it helps.

Cheers

Damir
