I tested raswin on Windows 2000 and it already looks quite good. Installation and starting from the windows start menu worked well. I did not find the rasmol command shell. How can I select residues ? If "copy" in menu edit is copying the image to the clipboard you should label it "copy image". I was wondering whether there is a new feature and I could copy atoms. Starting from shell: neither raswin.exe nor rasmol.exe is known. Installer failed to set the PATH variable. CMD.EXE: I could start it with full path c:\Programme\RasWin\raswin.exe. This is uncomfortable and users should be able to start it by typing rasmol. What is really nice is that it is accepting long file names for pdb files. I can use standard file separator (slash) and DOS file separator (backslash). After Rasmol started the shell prompt is not accepting rasmol commands as I know it from UNIX. The control is taken over by CMD.EXE again. CYGWIN-BASH: Rasmol application frame is comming up but I get a memory error and Windows closes the application. The mouse wheel is not working otherwise mouse controle is OK. I hope this helps Christoph
