I don't really know how to explain this, so I will as best I can. Since I've installed SP1, my explorer.exe crashes on a regular basis. I don't honestly believe SP1 is the problem, as everyone I've spoken to, as well as the other laptop I have, have never enountered any such problem. I don't quite understand why, but it seems as though MSN messenger might be causing the issue. I have my taskbar set to hide, and it gets stuck down for some reason. In any case, whenever I ctrl alt esc to get the task manager to come up, and someone IMs me on MSN (Causing the tasbar button to blink) it refreshes, and nothing is frozen for a while. After a bit of surfing and whatnot, it'll randomly get frozen up again, and sometimes I have to manually crash explorer.exe. If anyone else is getting this problem, or if someone might be able to help fix it, it'd be greatly appreciated. I'm relatively good with PC's and so on, but this has me stumped.
