nvPY Windows Undo & Redo works poorly (Windows Ctrl-Z och Ctrl-Y)

[magicnemo]

Try write below text in a note Hello all children

Select "all" with mouse and press delete & then without doing anything else press Ctrl-Z (undo), sometimes works ("all" comes back) sometimes nothing happends and sometimes the whole row disappears?? :) Other times text I previously deleted but now wanted back by pressing Ctrl-Y (redo), it was visible on screen / flashed by for some milliseconds but then went away, It was like nvPY had my text in memory somewhere but it just couldnt get it out & let it be visible.

I don't really trust Undo/Redo right now, should be looked into.

This is a thing to keep in mind, have documents backed up with versioning, Dropbox or Windows Versioning (snapshot).

Have no solution to this other than be cautious & make backups very frequently...

Undoing/redoing is broken on Linux too. Ctrl-Z undoes multiple actions at a time. Ctrl-Y seems to undo sometimes and paste text (?) at other times ... Does not seem to redo, however.

nvPY 0.9.4

Looks like there is a typo responsible for performing undo when you try to redo via the menu bar, but this doesn't account for all undoing/redoing problems.

Is the rest of it a Tkinter text widget bug?
