The problem is due to new event loop procedure on tcltklib.c. 
I wrote new Tk.mainloop method to avoid deadlock troubles on Ruby/Tk
and to get faster response for events. But it seems to have some faults. 
Although I'll try to fix the problem, maybe the work needs long time 
if the strategy must be changed. 

If your Ruby/Tk scripts have no trouble on old event loop 
and the trouble is more than you can bear, 
please replace tcltklib.c and tk.rb with those of 1.6.7.
