I have Vista 64bit and I find the reprap software has a few problems. Like I can't see the bottom of the window because it is off the screen and then random problems with the buttons. I don't know if these problems effect everyone or just a few, I know that being a open source project it is bound to have problems.

Which "the RepRap software" do you mean? I can think of four off the top of my head.

I did have some window sizing strangeness with RepSnapper on XP 32. Pronterface seems to have no troubles on that platform. I haven't tried Repetier yet, but it's definitely on my to-do list.

I have Repsnapper and Reprap host.
Repsnapper is ok but I don't think I can print with it as it doesn't turn the hot end off when it has got to temperature. Reprap host is almost useless as it doesn't show the temperature at all.

Is there a list on the wiki?

Once you set a temperature your microcontroller is responsible for maintaining that temperature.

I would recommend using Pronterface. [reprap.org]
