StatView 462E If you are experiencing erratic behaviour (non-repeatable crashes, etc.) while using a particular software package, follow these trouble-shooting steps: 1. Restart your computer with extensions off: System 6: Move the System and Finder files to a folder outside the System Folder and restart the computer. System 7: Hold down the 'shift' key during restart until the "Welcome to Macintosh, Extensions Off" dialog box appears. 2. Launch the program: If the behaviour has disappeared then you know that a file, or files, in the System Folder (System 6) or the Extensions folder (System 7) is conflicting with the program. In order to determine which files are causing the problem: System 6: Move half of the files in the System Folder into the folder which contains just the System Finder files (see Step 1). Restart the computer launch the program. If the behaviour reappears then you know that the problem was caused by a file which you moved into the folder before restarting the computer. Move half of these files back into your original System Folder. Restart the computer and launch the program. If the behaviour disappears then you know that the problem was caused by a file which you moved back into the original System Folder. Continue to move files by halves until the problematic file is located. System 7: Create a folder within the System Folder entitled Extensions Disabled. Move half of the files in the Extensions folder into the Extensions Disabled folder. Restart the computer and launch the program. If the behaviour reappears then you know that the problem was caused by a file which is still in the Extensions folder. Move half of the files remaining in the Extensions folder into the Extensions Disabled folder. Restart the computer and launch the program. Continue to move files by halves until the problematic file is located. If the behaviour is still present when you initially launch the program in Step 2 above: You should try reinstalling the program from locked disks. Remove any files that you wish to keep from the StatView 4.x folder then throw the program away and empty the trash. Reinstall the program from the original disks, making sure that the disks are locked (window on disk is open). Launch the program. If the behaviour is still present after reinstalling the software: It is possible that the original disks have been damaged. Virus protection software is one of the most common causes of a damaged application. If virus protection software was running during the initial installation and the disks were unlocked, it is possible that code was altered on the disks. Please contact us for replacement disks: statview@adeptscience.co.uk Other causes of erratic behaviour: Not allocating enough memory to the program when working with very large datasets and/or views or multiple files simultaneously. Running the program under low memory situations -- make sure that you always have at least 500k RAM free for the system. If you run multiple programs simultaneously or have increased the memory allocation to the program, it is important that at least 500k remain free for the Finder to use. Running the program on a hard drive which is over 95% filled. A hard drive may become fragmented if less than 5% of the drive is free/empty. Running the program under virtual memory, if more space was allocated as virtual memory than is available on the hard drive (e.g. 5 meg are free on the drive but 10 meg are allocated as virtual memory).
