Try to push Adobe to fix their Flash Player.
I know it hasn't much to do with Dell, but Dell has been busy to improve drivers for Linux by working in cooperation with developers like Ati, so let's give this idea a try:
I'm using Ubuntu 8.04 on all of my PCs and my laptop and it's a great operating system, but there's one thing I hate: Adobe's slow development of their Flash-plugin for Linux. Some bugs are in their plugin for years now, but it looks like Adobe doesn't want to fix them.
1) Menu's dissapearing behind Flash-object. For an example go to the website of ASUS:
Move the cursor to "Products" and see the menu dissapear behind the Flash-object.
2) Impossible to scroll when the cursor is on top of a Flash-object. When you move you're mouse to a Flash-object, you can't scroll. You first have to move your mouse away from the Flash-object to be able to scroll.
3) Transparancy won't work. When a Flash-object is using transparancy, you will see a white background, in stead of the underlying objects.
4) Sometimes Flash Player let's FireFox crash to the desktop. For example when watching videos at YouTube. After watching a couple of movies, FireFox crashes.
I've got these troubles on all of my PC's and my laptop, different versions of FireFox and different versions of Ubuntu. I hear a lot of people complaining about these problems, but it doesn't seem like Adobe wants to fix these problems. Maybe Dell can do something. I know it's not Dell's task to fix these problems, but they've worked with other developers to get better support for Linux and look at the big improvement Ati made in the last year (although I don't know how much Dell has to do with it).
