Tried a few searches here but didn't spot this anywhere.
Anyone else got this problem? I just tried to take a screen snapshot for the first time since installing iOS5 on my iPad1 and it doesn't work. (Worked fine with iOS4.3.5) Holding the Sleep/Wake and Home buttons at the same time eventually just brings up the slider to power off.
If it does work on your iPad1 with iOS5 please let me know then I know the problem is with my iPad.
