In the same yard sale where I bought Lotus SmartSuite '96 (whose Lotus 1-2-3 works under wine-20040615), I also bought the '97 version. I had numerous problems with the '97 version. Its installer failed while installing Word Pro (though it seemed to install Lotus 1-2-3). Lotus 1-2-3 fails with numerous errors when loading a small file or even starting without any file. Something (maybe heavier use of OLE?) changed from the '96 to '97 versions such that Wine is much less happy running the '97 version.
If anyone's interested, I can post more details. - Dan
