Just want to tell my experience with Wine and Newsbin.
First, the good news: It is running just fine now. Amazingly, even the thumbnails are displayed properly during download.
When changing the paths for "Download" data and "Application Data",
make sure that these directories are fully accesible by the user running
Wine. It seems Newsbin does not check whether the directories can
be written to, and it just won't store the list of newsgroups, etc.
It would be nice to have a simple checking done in Newsbin and deliver
an error message if writing in these directories was not succesful.
The MOTD display is not working under Wine. There are some messages that it requires ActiveX and one can load ActiveX and install that as a Mozilla extension. The program will even ask you whether you want to download and install the file, otherwise it could be installed beforehand, get the download from http://www.iol.ie/~locka/mozilla/mozilla.htm . However, once this is installed, Newsbin will still deliver an error message when MOTD is started and an empty window pops up. Fortunately, MOTD can be disabled after registering Newsbin.
There are still some issues with the display of the menus and the trees of the newsgroups, but one can find some workaround. For instance, dragging newsgroups in particular folders won't get displayed instantaneously, one has to use the expand function (clicking on +,-) to see that the move was successful.
I am still looking for a good native Linux binary newsreader, and I am hoping that Newsbin would be ultimately available also under Linux. Unfortunately, the binary newsreader for KDE, klibido, won't compile in my Gentoo Linux 2006.0.
