Apologies if this is in the wrong section, but I've been getting back into Pixelart again quite intensely lately, and I've been running into some problems with the software I use.
Primarily I use Photoshop CS2 which for the most part works perfectly. Annoyingly, however, it seems to be really, really inconsistent with registering clicks from my Intuos tablet, meaning that stippling pixel shading is virtually impossible, and even the simple chore of drawing lines is unpredictable and messy as the pixels aren't actually appearing.
I moved onto SAI and found it to be an extremely powerful and capable tool when creating pixelart, but unfortunately the one limitation I found with it was the most crippling - the eraser has no option whatsoever for disabling anti-aliasing. There is no efficient way to "rub something out".
I then moved to The Gimp out of desperation and spent nearly half an hour just trying to figure out the tools and found it to be equally confusing and limiting.
I'm at my wit's end here because I have no intention of slowing down in my pixelling, but my software is seriously getting in the way of productivity!

What do you guys use? And if you use the same programs as me, how do you circumnavigate these irritating shortcomings??
Thanks in advance.
