Ok, Access MDB iw a windows app. So is excel and Word but OpenOffice still has replacements that do most of the work. All I've got for Access on Linux is a viewer.
I may be an exception here in that I do use Acess (and almost never Excel or Word). It would still be nice to have Access as well, so I could manage 15 years worth of databases without having to revert to windows or wine.
Having copied several of the genealogy CDs now it's looking as if the majority are PDFs with a few text files thrown in. One is an Access read-only database but a couple more are proprietary. Just installed wine to see if that will work.
Despite my (small) problems trying to run windows software, I do think there should not be a windows portal installed in linux. There are far too many potential ways into windows and adding something that could work back to linux is scary. Or perhaps I'm reading more into this than I should. :(
