[Uim] Die, .uim file, die!

[Dave M G]

UIM mailing list,

I am using Ubuntu Dapper 6.04, and I have UIM/Scim/Anthy set up for 
Japanese input for within my largely English operating environment.

Using the UIM preferences tool, I have made some custom configurations 
which I find more comfortable. For example, I have set [ctrl]+[space] as 
the keyboard shortcut keys for switching inputs, instead of the default 
[shift]+[space].

It's almost working perfectly.

The problem is that every time I reboot, a file called .uim gets created 
in my home directory, and this file over-rides all my customization. For 
example, the keyboard shortcuts return to [shift]+[space].

Through experimentation, I have discovered that simply deleting this 
file will restore my personal preferences.

Obviously, it's not ideal to have to delete this file every time I reboot.

I have tried leaving the file in place, and using the preferences tool 
to reconfigure my settings, but this file accepts no changes.

I don't know why this file is being created every time I reboot, as it 
clearly is not needed for the successful operation of UIM/Scim/Anthy. I 
don't know what process is creating it, or why it is determined to force 
the default settings.

My local Linux users group and the Ubuntu mailing list were not able to 
help on this, as no one seemed to fully understand UIM.

How do I stop this file from being created, or stop it from over-riding 
my personal settings?

Please be aware that I am no Linux guru, so newbie-friendly explanations 
would be much appreciated.

Thank you for your time and advice.
