Changed icon's reverting back to original.

Hi,

I like to keep my dock fairly well organised as theres a lot on it. In particular I like to assign individual icons to a range of word and excel files. I've changed the icons by simply right clicking on the file, get info and then selecting and pasting the new icon over the old one.

That all works fine but then after a random amount of time the icons revert back to the way they were (the original word/excel file icons). What could be causing this and how can I stop it from happening? Sometimes it happens after a restart, sometimes I just notice they have changed back without a restart (at least not that I can remember restarting it anyway).

Thanks,
Rueffy.

No the files are located on an external hard-drive that is always plugged in. I think it was happening when the files were located on the computers internal hard drive anyway.

I use Onyx on a fairly regular basis anyway and that includes the cleaning of cache files, I've just gone through and done it again but I don't expect any success.

No luck with the cache clearing. The icons have reverted back. Any other suggestions?
