- My mother's PB 170 4/40 w/ Apple modem had trackball and button problems
- a couple months ago which were as follows:
-
- - clicks on objects would not be registered appropriately occasionally,
- in a variety of applications: I tried it and so noticed the pointer
- was right on the object being clicked--just nothing happened
- - the arrow cursor would move jerkily around the screen, as if the
- trackball was dirty or as if the machine was doing a lot of background
- work. No, the machine had not gone to sleep, and power-saver was
- turned off, and the trackball was clean (she hasn't used it that much,
- either, to make it terribly dirty).
-
- She sent it in and they replaced the trackball which SEEMED to fix the
- problem. However, while playing with SimCity (1.4, the monochrome version),
- I noticed that again, with power-saver off, if I
- leave the trackball alone for a couple seconds, the machine goes into
- super-slow mode: the animation all but stops, and the progress of the
- simulation becomes about 5 times a slow (there's a counter indicating
- the passage of simulated time). Simply moving the trackball a bit
- will restore it to full speed, and continuously moving the trackball
- (going in a circle, for instance), will keep the game going at full tilt.
-
- She mentioned that a problem she'd had before having the repair dones
- was that the insertion point in MS Word 4.0 would stop flashing, and it
- would take the machine a while to catch up if she started typing. She
- also said the problem seemed to occur only after the machine had been
- on for a while.
-
- It sounded to me like an ADB problem, but I don't know that much--are
- there faulty trackballs which bog the machine down or cause missed
- mouse events? Anyone else have these problems?
-
- I believe the only INITs are the Apple Fax, Quicktime, and ARA; she
- had tried it with them all disabled before sending it in, also.
