Appendix D: TroubleshootingFigure D.2. Canary’s Info window. The exact layout <strong>of</strong> the window dependson which version <strong>of</strong> the sytem s<strong>of</strong>tware is running.You can increase the amount <strong>of</strong> memory that Canary requests from the operating systemby simply editing the Preferred size (or Current size in older versions <strong>of</strong> the System 7)value in the Info window. Note that you cannot change the Preferred size value whileCanary is running (although you can view the Info window at any time).Solutions to inadequate memory conditionsBelow are several potential solutions to inadequate memory conditions. Note that youmust quit from Canary before you can try any <strong>of</strong> these (with the exception <strong>of</strong> #1), sinceyou cannot change a program’s memory allocation while it is running.1. Close unnecessary windows. Every window in Canary uses up some <strong>of</strong> the allocatedmemory. How much memory a window uses depends principally on the signal length,on whether a spectrogram has been calculated for the signal, and on the spectrogram’sgrid resolution. Closing unnecessary windows frees up memory within Canary’sallocation block.2. Increase the amount <strong>of</strong> memory that Canary requests. Change the Preferred sizeparameter in Canary’s Info window, as discussed above.3. Make sure you’re using 32-bit addressing. This is relevant only if you have morethan 8 megabytes <strong>of</strong> RAM installed. The Macintosh can operate in either <strong>of</strong> two“addressing modes”, 24-bit and 32-bit. In 24-bit mode, the system can only use up to 8megabytes (irrespective <strong>of</strong> how much RAM is installed in the machine). In 32-bit mode,the system uses all <strong>of</strong> the memory you have installed. System 7 allows you to choose theaddressing mode, via the Memory control panel (usually on the apple menu). The onlyreason to ever turn 32-bit addressing <strong>of</strong>f is that some older Mac programs areincompatible with 32-bit addressing. Note that if you change the addressing mode withthe Memory control panel, you must restart the Mac for the change to take effect.Canary 1.2 User’s <strong>Manual</strong> 221
