how large are the files in question? and how much data are you pasting? pasting the strangely formatted code:
for(i = 0; i < 20; i++)
{
printf("hello, current counter %d\\n", i);
}
in at the end of this 23,000 line file is not producing any flashing.
what happens if you highlight a block of code and tell the IDE to format it? i believe this is basically all VA is doing.
