I'd type the fractions, the calculator would automatically switch to fraction mode, and then I had to switch back to decimal mode in order to be able to enter an exponent a little later. Next time I entered a fraction, I had to switch back again. I don't remember precisely but it could've been measurements like 1/64 inch mixed with metric data that I normally convert everything into.

OK, that's solved easily: Assume you have some calculation like 4 1/64 * 5e-3 + 1 2/3. Then I'd recommend to solve it this way:

64 1/x 4 + 5 EEX 3 +/- * 1 + 2 ENTER 3 / +

No need for fraction mode, no switching between modes (that's a quick and easy solution - in the long range, get rid of measures requiring such fractional values ).

As I wrote before, fraction mode is designed to deal with fractions - i.e. to help students (pupils?) who have to calculate using them. That's one reason IMHO why fractions appeared on HP calculators not earlier than the HP-32SII - they aren't really needed in professional life.
