Flash problem

[0nKILL]

not sure if i should post this here

For now i am doing all my stuff in flash, I am about to get a new computer and on that i will add photoshop and other programs but for now i am training my tablet skills on this portable computer.
Thing is, this shitty pc is making it hard to actually do anything in flash.

In this pic below, i show where the lines have automatically gotten wrong proportions, super thin,fat or copletely erased and sometimes even worse (The sad face on the bottom wass a pretty perfect circle until i released the button...)

is this a normal thing with flash? or do i just have to get a better computer?
a friend told me that the tablet might have some sort of pressure thing so the lines get thinner with less pressure and thicker when i put more pressure, i tried that but it did not have anything to do with it.

Here is info about my pc, and my tablet is a Bamboo

...i dont know, if you got a solution to this or experience the same problem, feel free to post.

It looks like a problem with the smoothing. Try adjusting that, see if it helps.

That's completely normal, its just that the brush tool in flash can be kinda crappy sometimes. Try dragging down the smoothing to about 40 and activate the pressure sensitivity if possible.

thanks =) it works a bit better now, how do you change that pressure thing tough?
