I am running LT2004 on XP-Pro I have no problems with drawings that I or others in the office create however on occations with drawings from some clients I experience the following. Within the Plot dialog window and selecting the "Plot Device" tab. The "Plot Style Table" drop-down has two options None or monochrome.ctb (missing) My .ctb files are not offered as options for selection????? and the monochrome.ctb is in the defined path? Info - My .ctb files are not in the default path but in my own folder which is defined in the "Options" dialog window, - The standard AutoCAD monochrome.ctb is also located in my folder. Any suggestions. Thanks in advance.
