Plot Style Settings

[jrevait]

Hello,

While trying to plot a drawing I've been unable to access the .ctb files (ex. monocrome.ctb) within the 'plot style table (pen assignments)' in the 'plot' window. When I use the pull down menu all that is shown is .stb files which are not plot styles, even though all my .ctb plot styles are in the proper folder on my computer. This only happens from time to time but it is increasingly annoying. Does anyone know how I can make these .ctb files show up in the pen style table?

Thanks in advance... Jamie
