| 49278 | 2002-05-17 05:08:00 | I am using a two button serial mouse. When loading applications or opening a new window the mouse will pause or stutter until that window has finished loading etc. So obvously this has something to do with Harddisk activity. The question is why does the harddisk activity effect my mouse. | Guest (0) | ||
| 49279 | 2002-05-17 05:52:00 | Is the serial port on a standard ISA IRQ, or is it sharing a PCI interrupt? Seems unlikely, but this *is* a computer, and anything can happen. If it is 'standard' the disk shouldn't affect it. If it shared the same interrupt, the disk would be serviced preferentially. |

| 49282 | 2002-05-17 11:19:00 | I'm using a doorstop of a pentium, it is but a 450meg chip on a really old mobo. The mouse is PS2. I am doing far too much on it, 12 windows open as i type to give you some idea.. I used to have a similar problem, i still do when i do huge photoshop things that no-one in thier right mind would do on such a slug. Esentually i solved the problem when i upgraded from 64meg of RAM to 256. and now it is only when i do the extreems of rediculous that the mouse responce is paused or stuttered. I could be wrong, but i think my machine was far too busy thinking to be concerned with the trivialitys of moving a curser around the screen. Does this sound familiar? |

Any (after the first) which come in from the mouse in this time are not queued up or saved . You could try changing the mouse settings so that it does not interrupt so often (that is, make its resolution coarser). That will cut down the number of intterrupts which will be lost, and smooth out its operation. |
