Hey Jack, I have WIN98 on no less than 4 machines! Have had Poser 4 on all of them at various times. Never noticed any of the changes you mention when I upgraded from 95. In Poser anyway. I have had other problems off and on, though, too numerous to mention, with various other programs, most noticeably a Wacom Intuous tablet that needs its dat file rebuilt about once a month, without fail. Strange, perplexing, and still sometimes pleasing creature is WIN98 (not a first wife, though I had one of those too). Despite all this, I can only advise you to perservere. Or change OS.
