When installing Sirocco software on a machine that has had a Palm installed, the following file is placed in the SYSTEM32 folder in the Windows directory. For some unknown reason, Sondigo software cannot make the distiction between the USERDATA.DLL file in the SYSTEM32 folder and the one in the SYSTEM folder, complaining that the procedure entry point is invalid, which it would probably be if acessing the Palm DLL. This might be a registry issue as well....
If you rename the Palm USERDATA.DLL in the SYSTEM32 folder to USERDATA_xxx.DLL, Sirocco works as advertised, but you'd most likely lose the Palm functionality.....
