I think these are unexpected behaviours (that I can easily reproduice on xiphos 3.1.4-mozembed under Ubuntu 11.04) :
1) Move the left vertical separator (between the left pane and the Bible one) full left.
Now stop clicking (with your mouse) you will have a strange behaviour.
Indeed you have a strange mouse...
(The problem does not happen if you move the separator full right)
Same problem with the horizontal separator between bible and preview.
2) If I want to hide the dictionary (not using the menu bar) but with the mouse and the horizontal separator (in the right pane), it works perfect !
But If I restart Xiphos, I have the top of the dictionary displayed, in the status bar !
3) It is impossible to hide the right pane, which contains commentaries/books and dictionaries, only with moving the vertical separator.
Is that clear ? Can you "reproduce" it ?
I don't know, this is easy to solve or not, but I reported it because I think these are strange behaviours.
Sory for my very bad English
And thanks for this software
