Ditto, it's working quite well with crossover 4.2 standard under SUSE 9.3pro and KDE, in single-user mode, on IBM R50 Thinkpad. Annotation Tool,Text Touch-up Tool, Forms Tool (adds Text Fields), as well as Page rotation, deletion and insertion all seem to work normally, so does the Distiller (direct .ps -> .pdf conversion, launched separately). Pretty impressive considering it is an unsupported application. The only problem I have found so far it that the menu items in the Annotation Tool dialogue box are truncated.
