[Wine] Pegasus Mail and Wine

[Rosaria]

Hi
I have installed Ubuntu 8.04 "Hardy Heron" released on april 2008. 
The kernel is 2.6.24-19. 
I have installed Wine version 1.0. 
I want to use Pegasus Mail 4.31 for my personal e-mail. 
I did several attempts with various version of client and wine (old version too, until 0.6) but I always obtain the same error. 
The error is this: when I send a message the composition window closes so the whole application do. 
Do you have suggestions to give? 
Thanks
