[PD] pdx problem with tk externals

[Patrice Colet]

 Hello,

trying several gui objects like #many or flatgui/popup or tof/menubutton on pd-extended results in error messages
that doesn't appear on vanilla, this is still under win32, there is definitely something wrong with tk on windows pdx, bugs appearing after a while, when working in subpatches, spacebar is creating empty objects, so hard to reproduce... If it continues like that pdx interface will be so hard to debug ;) please stop to add features, and start to debug the stuff, sorry I've no time for helping actually...
