mysteriously auto shutdown in Replgo 2.1, N7610 4.0441.0ch
my Nokia 7610 OS version is 4.0441.0ch, and the .rgo filenames are in Chinese. but if I am looking at the rgo book on my mobile in a flowed & fullscreen mode, then when I press the right " return " key on the phone's keyboard, the Repligo will often mysteriously auto shutdown without showing a file list.
And furthermore, this happened on some rgo files with long Chinese filename, but if I rename them into short ones, it would be OK for a short time. And soon the problem would happen again if the filename is longer than 5 or 6 Chinese characters.
But some files with Chinese filenames are always OK even they have long filenames which are about 8 or 9 Chinese characters or longer.
And after some trials, this would also happen in some files with long English filenames, and irrelevant with the file size.
The Repligo in my phone is V2.1, the latest English version.
Could you please kindly help me ?
