Appendix D TroubleshootingAbout this appendixThis appendix lists solutions of some of the most common questions that are likely to arisewith Canary. If you encounter a problem that is not discussed here or in the relevant chapterof the manual, you can request technical assistance by posting to the Canary online userforum at http://canary.RavenSoundSoftware.com/. The Bioacoustics Research Program isnot actively supporting Canary since the software was made available for free on the BRPweb site.Known Bugs• Double-clicking a Canary file launches the program, but the file doesn’t open.This is a known bug that occurs only on PowerMac machines. To open the file, eitheruse the Open command from Canary’s File menu, or double-click the file’s icon againonce Canary is running.• Switching off one of the two tracks in the record dialog results in the two stereoinput channels being mixed on the remaining track, instead of turning one channeloff completely.This is a known bug that afflicts some Macintosh models with stereo recordingcapability. The solution is simply to provide a zero (silent) signal on the channel thatdoes not carry the desired signal.Speed and memory• Canary never seems to have enough memory.Some background about Macintosh memory allocationWhenever you launch Canary (or any other program), the Macintosh operating systemallocates a certain amount of memory (RAM) for the exclusive use of that program. Theamount of memory that is available for allocation to a program depends first on howmuch memory is physically installed in the machine and second, on how much of thatmemory is already allocated to other programs (including the opearting system). To seehow much memory is installed in your machine (“Total Memory”), how much isavailable (“Largest Unused Block”), and how much is allocated to each program that iscurrently running, select About This Macintosh... from the Finder’s apple menu (FigureD.1).Canary 1.2 User’s Manual 219
