The most probable thing is that you have defined a method called "raise" in
your program. But, the error procedure which popup a window (and which is
written in Scheme) overload the Tk command raise.

Two ways are possible to circumvent the problem:

        1. Rename the raise in the file Lib/error.stk to Tk:raise (which is another
name for the Tk command raise)
        2. define a method for raise which will call the standard raise if
parameters don't match the method you have defined. Something like
                (define-method raise l
                        (apply Tk:raise l))
should do the job.


First solution (i.e. prefixing all the Tk commands with "Tk:") is clearly my
work (it is on my TODO list since a long time)

Second solution has the advantage to bemore general.
