GRAPH effect mode and distribution buttons with script loop

[rodericwilson]

not something serious but i was using the new graph effect and had a script loop going changing the height ,width and pitch and for some reason the graph mode can't be changed while the script is running ,neither can the distribution buttons of height ,width and pitch be changed .
the buttons seem to flicker .
also i have experiemced this button flickering before when i have a certian script (with the layer fx button) but the fx work fine .is there any significance in this flickering?

the sort of script i wrote was like this

void PreRenderEffect()
{
SetWidth(x);

x++;
if (x==100)
x=1;
}
