Revision History - v6.01

Daqarta v6.01 - 14 April 2011

Bug Fix: Generator crashed when loading Play Wave files.

Bug Fix: If Daqarta was active when entering Windows Sleep or Hibernate modes, it could cause a long delay when Windows resumed operation.

Bug Fix: Wrong cursor readout Y values during DDisk file position changes if non-zero Cursor Time Constant.

Bug Fix: Frequency Counter did not work properly in some Decimate modes, and triggered waveform display was unstable.

Bug Fix: Sigma readout in Exponential mode of Wave Averager always read 0.00.

Bug Fix: Could not load .CAL, .CRV, or .LIM files having values with more than 16 digits.

Bug Fix: Position/time readout for DDisk recording or file reading was multiplied by Decimate Factor even when Decimate was inactive.

Bug Fix: Possible program crash on Dual, Solo, or Swap toggles if Wave Block KB = 2 and both Left and Right Generator outputs active.

Bug Fix: Triggered Waveform display alignment was off by one sample compared to X-axis markings.

Bug Fix: A noise source set to Copy another (including shifted copies) could mis-track after a control change.

Bug Fix: HelpAbout macro did not work.

Bug Fix: Certain macros using WaitMsg in a long loop could fail to respond to the Cancel button.

Bug Fix: Macro Halt and Cancel buttons are now properly shown as disabled when no macro is running.
