Using 2.0 on an 8830 w os 4.5 I get an error code when trying to open the folder containing an ebook in which I have played one chapter. The error is
"there was an error performing this action: java.lang.illegalargumentexeption: null"
closing podtrapper and reopening doesn't help although I can get into other folders.
I've found as well that when playing a file that I cannot delete the file unless I shut down podtrapper and restart or I get an error code (although I didn't happen to write it down)
