IDA Pro noob here. I hit a wrong key while trying it out and now some of the lines that looked like
lea ecx, [esp+150h+var_13E+2]
now look something like
lea ecx, [esp+14h]
It computed the sum of the formula to figure out the stack address, removing the stack variable name it was using. It's harder to use now. Is there a way to get back the original line?
