Changing to an Intel Mac lets Lyx forget settings -- any hints?

[Christian Liesen]

Hi,

I've just got myself a new MacBook Pro, which feautures the Intel Core 2 
CPUs. I had a PPC Mac before and transfered all data using the Apple 
standard feature, i.e. connecting both machines with a firewire cable 
during setup of the new machine and voila!, everything's there. Both 
machines had OS X 10.4.8 installed.

Now there's something weird about Lyx. I updated to the version for 
Intel-Macs, but Lyx has forgot about all the settings. It doesn't find a 
single viewer, nor a single document class -- they're all marked as 
"unavailable" in the Document Settings dialogue. It does remember my 
documents, though.

I'm a little confused about this and don't know what to do. Do I have to 
reinstall TeX?

Any hints would be highly appreciated.

Thanks,
Christian
