FlowCE 2.2.4

FlowCE 2.2.4 fixes quitting. Since 2.0, 2nd quit could restart the calculator ("Validating OS...
Calculator will restart when validation is complete"), bring back TI's "PRESS ALPHA F1-F4" help
screen, or leave the calculator in an odd state. FlowCE now hands the calculator back cleanly.

It also no longer crashes when the calculator's RAM is nearly full: FlowCE now reserves its working
memory when it starts, and uses less of it when RAM is tight. Everything else is 2.2.3. FlowCE
Python 1.9.1 is unchanged.

Install from the website and pick a version.

Checks

• On an emulated TI-84 Plus CE: quitting traced step by step (the calculator is handed back the
  normal way), quitting and turning the calculator off and on again many times, 61 to 130 KB of
  variables in RAM (64.5 KB reset the calculator in 2.2.3), the 898 regression problems (the same
  answers as 2.2.3, none hung), interrupting with on, out of memory (8/8), 101 screen checks, 29
  ways through the menus, and the 71 applications problems.

Please report problems with what you typed
and your calculator's OS.
