Dear all,

I started to try to make BLT 1.8 to work with STk 3.0.

Being mainly interested in drag & drop, I tried first the following experiment:

1. I tooked the BLT 1.7 for STk distribution, and I disabled the compilation and
linking of all the modules except drag & drop using the options -DNO_<module>.

2. I got the from the 1.8 distribution.

3. After having re-formatted the code (the formatting is different between the
two versions), using the file-merge tool I have put the 1.8 changes in the
bltDragDrop.c of the BLT-STk distribution. The changes are:

4. I compiled and linked the code. All worked fine (no warnings).
5. Finally I tried to use drag & drop, but pressing the right mouse button 
nothing happens.
What is wrong? Any idea.
I do not know if the problem is in the C code or in the scheme part (I have not 
changed it).
Can someone help me?
Thanks of all
Giorgio
