- In our lab we have a Quadra 900 which selectively crashes by ignoring
- mouse movements. This is a repeatable occurance.
-
- Hardware: Q900 with 12M RAM. Internal hard drive, freshly formatted.
- System 7.0.1 & TuneUp 1.1.1, freshly installed.
-
- Crashes with Apple extensions only enabled. One way to make it crash:
- Open the alarm clock DA, turn on balloon help, mouse over to alarm clock,
- instant mouse freeze up(cursor position freeze actually, the mouse clicks
- still get through). Also crashes by opening(and closing) windows in the finder
- for a sufficiently long time(running NO applications!).For clarity:
- the crash can occur after having rebooted and having run no application.
- Finder operations are sufficient to cause crashes. Only the standard
- system extensions are installed. No VM.
-
- The peculiarity: ONLY occurs when the cache is ON(set by Cash Switch DA).
- No difference is seen in 24 or 32 bit addressing modes.
-
- Any suggestions for remedies before I truck it over to my trusty repair
- center? I.E., can this be a hardware problem?
