screen shot of initial config screen

Claws Mail 3.8.0  Ubuntu 12.04.1 Desktop
Claws Mail extraordinarily aggravating error sequence.

Ubuntu Desktop 12.04.1 recent install


Claws Mail opens normally 
Configuration>Filtering   : opens ok

Filtering configuration - form
typein Name  ok
click in action then click on define button ok
select move select folder ok
click in Condition ok
click define ok
click match criteria select header select name "From" ok
pasted in address ok
clicked Add  ok
Now the Name, Account, Condition, and Action fields are all complete ok.
Now click Add (filter) ok (it shows up in the list of filters)

Now starting the process over without leaving the Filtering configuration form.

Typein new name for this next filter ok
clicked action>Define button ok
clicked Action Button select Move ok (move is the default anyway but I select anyway) ok
click in Desination click Select button ok
Select Folder form is open ok
Click on New ok
New Folder Form opens ok
click in Input the name of new folder form field and cannot type  
cannot even see the mouse cursor inside the form at all after the initial click.
click back onto desktop and then back on any of the five claws mail window and
the Input new folder form is highlighted, but mouse is not avaiable, and keyboard
input does not work, either, even though all visual indications show that the form
is ready for input from the keyboard.
cannot type into form
cannot cancel
cannot click ok
cannot click x to close that form
cannot close any of the five claws mail windows
the only way out I've found is to logout.

This does not happen every time, but almost always the first
time or the second time.

Almost every time the problem occurs it is in the Action Form.
Move is the default, but if you click on it, and it's going to hang up, you get nothing when clicking.  Clicking on any other portion of the form does nothing.
Clicking in any of the other 4 windows open does nothing.

This would not be nearly as aggravating if you could just close Claws Mail and restart it, but the only recovery that seems to work is doing a user logout and login.  Then start Claws Mail.

Best Regards, 
Jim
