Eq issue

[Noitarud]

Maybe this was deliberate, or not, but if I enter 1+1 and repeatedly press = it will eventually enter. Maybe:

• disable entry if having to do a sum
• enter based on whole keyed string, even if more complex like "6/7.0="

also could make calculations deliberately a bit slower, like 0.5 sec per calc.
