When enabling the automatic backup (Options | Automatic Backup), selecting a directory then delete this directory in Windows Explorer the following behaviour is observed:
An error window with the title \"wt\" comes up which includes \"[MAKELOG_do]\" and an error message which is bilingual (selected lanuguage from Win-Test and OS language).
This error window occures mutliple times (on top of the old ones) - each time when the backup fails. It would be more convinient if it would not appear again if the \"same\" window is still open.
Another (external) window shows up also with the title \"wt\" which asks \"Do you want to disable the next automtaic backups, if any?\". Choosing \"Yes\" does not change the behaviour, the automatic backup is still enabled.
