Sentry Crash Report:

Description Juergen 2010-06-03 05:50:28 UTC 
Version:           0.9.3 (using KDE 4.4.2) 
OS:                Linux

When by chance Parley is started twice because the launch button is pressed double (double click instead of single click) two instances are running. If the user in one instance makes changes or practises the changes are written on close or save to the language file. 
If the user after closing the second instance (where s/he just work in) discovers that there is a second instance running s/he will simple close this. But doping this will overwrite the language files with an old version and all changes are lost

Reproducible: Didn't try

Steps to Reproduce:
Open 2 instances (I am working on Lucid 32 bit) of Parley.
Work on one and save the changes. Close Parley.
Close the first one.  


Actual Results:  
The changes or the second instance are annulled.

Expected Results:  
Parley should not open 2 instances (processes) but check if there is already one open and use this one.
