Computer bugs: what's annoying you most?

for my work PC, it would be the internal email system. for some reason it can take almost a minute to open up the address book or even a simple mail.
other than that they're fairly robust and bug free.

my home pc on the other hand, oooh......

Right now, for me, it's the little incompatibilities between different MS products. Specifically, between Excel 2003 and MS Virtual Desktop Manager.

Now, every other part of Office will co-exist quite happily with MSVDM. Everything else on the computer does, in fact. But Excel doesn't. If you try to use both together, then as soon as you switch between virtual desktops, all your Excel windows lose all their toolbars and menu bars. Grrrrr.

The comp (or program(s)) takes a long time to start up. This isn't really a bug, just showing its age. But that'll be solved soon as I'm expecting a new comp soon. Hurrah!

The worst is iSIGHT webcam/iCHAT doesn't work with the latest version of OSX! hahaha How ridiculous is that? You can't audio/videochat. I can only get around it by using Yahoo for the camera and then Skype for an audiochat.

My home PC reboots itself with no warning and for no apprent reason every few days. Otherwise it's remarkably well behaved.

Oh, and another thing: Lotus Notes and its attitude to the focus.

Every other program ever written for Windows ever expects Windows to put it to the front of the z-order list when it gets the focus.* Lotus Notes - and its related program - doesn't do this. When Lotus Notes gets the focus, it immediately pulls *itself* to the front, covering up everything else.

Now, for 99.9% of users this won't be a problem, and they won't notice any difference between this behaviour and the way everything else behaves. However, if you've installed the XMouse PowerToy, it's fucked-up. The whole point of installing XMouse** is that you can give the focus to windows whilst they're still partially obscured by others. Lotus Notes' behaviour is very, very annoying.

This probably seems like a tiny technical point. It's not, though. It means that the only way to get any work done if you've got Notes open is to minimise it when you're not using it. If you've got it open but are using another window in front of it, then it only takes the slightest slip with the mouse and - oops! - Lotus Notes has covered up everything else on the screen. Grrrrr.

(Of course, both of these annoyances are caused by me trying to make my Windows machine more Unixish. I'm using Microsoft products to *do* it, but it's still making the computer behave in a radically different way to most Windows installations)

* for non-geeks, this means: when you click on it it's pulled out from behind everything so you can see all of it - and it's Windows that does the work normally.

** other than "wanting your Windows computer to behave more like the Linux computers you're used to", which is why I did it
