CHIUSYSTEMS  Hi Funderburk, thanks for letting us know about the problem. May I ask what version of OSX are you running (10.x, PPC/Intel)?  
(Version 1.02)

FUNDERBURK  My system is 10.4.8, Intel Core Duo with 1GB memory.  
(Version 1.02)

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.

FUNDERBURK  "which bc" shows "/usr/bin/bc" and I have used bc from the command line before. Is there a log file generated anywhere that I could retrieve additional information for you?

CHIUSYSTEMS  Hi Funderburk, if you go into terminal and type "cd /Applications/BiM.app/Contents/MacOS" then "./BiM" you should be able to see any errors that are printed.

You may need to replace "Applications" with where you have BiM installed.

If you can send your results to contact@chiusystems.com we'll be happy to send you a serial number for all your trouble.

Thank you for your patience with the issue.
