how to reproduce;
resize "Server Name" to something noticeable
sort "Files" by highest to lowest
sort "Upload Time" by highest to lowest
shutdown aMule (exit gdb)
start aMule
now the "Server Name" column is smaller then what I set it
the serverlist is now sorted by "Users" not "Files"
and uploads are now sorted by "Status" not "Upload Time", like I left it.
(some other columns revert to default position too, but this was just an example)
using aMule SVN wxGTK2 v2.8.8 (Snapshot: Fri Aug 29 07:02:10 CEST 2008)
