No, it means fixing EasiWriter. Done.
But somehow I am still puzzled. I could reproduce your problem, but
only with an extremely verbose directory structure. It still works
fine when exporting to:
ADFS::Toccata.$.Test.EasiWriter.This is a long directory name.longer than
should be allowed.But not deep enough even.How could that happen
but it fails when exporting to
ADFS::Toccata.$.Test.EasiWriter.This is a long directory name.longer than
should be allowed.But not deep enough even.How could that happen.I cannot
believe your structure is that deep
I need to extend the Filer window to almost the complete width of the
screen just to see the full pathname. Are you seriously using such a
long directory path? It takes a target directory name with almost 200
characters to make it crash. Anyway, it will be fixed in the next
release version.
A word of warning: This is very close to limit in the RISC OS data
transfer protocol. You should expect practically all applications to
go wrong when your pathnames get just a bit longer. In theory, RISC OS
allows 256 characters but in the desktop, only 212 are allowed.
