Crash after autocorrect options and closing application - still there
The known bug that LO crashes after changing autocorrect options and closing the application is active in both versions of portableapps, i.e. the current 5.0.2 and the previous 4.4.5.
The horrible autocorrect makes the writer app nearly unusable, so you must turn off autocorrect before writing and turn it on before closing the app. Otherwise, the app crashes. In any case, it is impossible to start writer without autocorrect enabled.
For the time being, OpenOffice seems to be the only viable workaround. Maybe there should be a LO with autocorrect disabled by default.
