Sometimes, when I make a selection and use a Gaussian blur or similar filter on that selection it will take the pixels outside the selection and average/blur them in, so that the selection is contaminated, when in fact the reason I made a selection is to apply the filter only "inside".

It shouldn't do that. Try deleting your prefs file and launch PS so it can create a new prefs file. (Save a copy of the prefs file in case this doesn't fix the problem.)

EDIT: This is what should happen when you blur inside a selection:

If the blur strays outside the selection, something is buggy. As I suggested above, try getting rid of the preferences file and see if that kills the bug.
