Problems with snack and wavesurfer

Wavesurfer and Snack (latest versions) do not run properly with tclkit-8.5a6 on winXP. They seem to run ok on Linux 2.6 with tclkit-8.5a6.

To duplicate the problem one can try running the wavesurfer demos; the waveform display does not appear at all. Other programs using Snack, fail as well (crash).

Running the same applications with tclkit 8.4 on both OSs is ok.

I don't know if it's tclkit or tcl 8.5 that's causing the problem though. Or if Snack needs to be compiled with tcl/tk 8.5 sources.
