Understood perfectly. Java has always been kinda kludgy in the UI realm, and has often been slower than dirt IMHO - no wonder you were worried :) (and if they tried to get all happy with Swing, then... groan.) What the URL of the modelling proggie? I'm kinda curious to see what it does do (under both Win32 and Linux VM's, natch.) (Strangely enough, when I run Poser 4/PPP under Win4Lin, I do get wheel mouse support... seriously. It's because the mouse's wheel calls from the kernel I/O are most likely intercepted, then converted into arrow keystroke calls before Win4Lin's Win32 shell sees it. Win4Lin was built from the old SCOMerge proggie when the original SCO went under...)
