instant preview & advanced replace

[Tommaso Cucinotta]

Hi,

when replacing with advanced find and replace, and instant preview is 
active, the preview-ed math elements don't get updated with the replaced 
contents.

How can this be fixed ?

I guess that, at the end of findAndReplace() in lyxfind.cpp at line 
1345, I'm missing something to update the previewed insets that have 
been affected by the replace operation. For now I have a

    bv->processUpdateFlags(Update::Force);

which is obviously insufficient.

Thanks, bye.

    T.
