CHIUSYSTEMS Hi Funderburk, unfortunately we have not been able to reproduce the problem you have described. The only possible cause, according to our developers, would be your copy of OS X missing the default bc program. If you open terminal and type "which bc" (without the quotes) it should show "/usr/bin/bc". If not, then that is the problem. If the terminal check works, then we really don't know the problem. But as a tip, quick calculations can be done without BiM by typing "bc -l" in terminal to use the regular command line version. (Version 1.02) |
