[Scilab-users] Problems using save

[Matiasb]

Thanks Ezequiel! Samuel, you were totally right, so many thanks ;-)

Upgrading to 5.5.2  it solved the graphical window and it now allows me to
save matrices in the files.
Saving work relatively fast and loading afterwards takes quite long (the
saved file that is produced is aprox 50MB), but it doesn't seem to be
leaking memory any more.

Thanks again!
Matias
