GIMP :: Fuzzy Select Tool Selects WAY Too Much Even At Threshold Of 1 At 2

i tried restarting gimp but it did not fix my problem. All of a sudden, out of nowhere, my fuzzy select tool selects WAY too much even at a threshold of 1. at 2 it just selects the whole picture.Re-installing did not fix.

i am creating black/white based icons. So it is a 48x48 image. i am mainly trying to fuzzy select black, white, and transparent selections. As you can guess, it has become impossible now and i don't know what i did.

EDIT: Okay so it actually isn't selecting "too much" per-say. i willt ry and explain the best i can here:

Black and white image with the exception of some shades inbetween.Select fuzzy select and put threshhold at 1. Click. Selects all the white (i actually think it misses some). i hit SHIFT and click on a pixel that is slightly not white. VERY SLIGHTLY. In fact, it may actually be white. It fuzzy selects EVERYTHING.

Another example on an image that is Black and Transparent (with shades inbetween) Slect black on threshold 1. It selects All the black AND all the shades inbetween. Eveything except flat out transparent. i hit CTRL and select a shad einbetween and it deselects everything.

EDIT 2: Doesnt matter the threshold apparently. It will do this on any.

EDIT 3: The solution, after all, was so save these problematic images as JPG and then open them as the JPG.
