Hello,
 
Have error '"" is not a valid boolean press OK...'. This appears after the log pannel opens and just after the Detail window appears. Only occurs on my Mint 17.1 system. Happens each time CQRLoads. If I press OK the program loads and so far appears to work. Just upgraded and will continue to exercise the program. Data file appears to be intact.
 
My other PC is running Ubuntu 14.04 and does not exibit this error,
 
73,
