NanaZip freezes when the path that explorer is open in becomes unavailable

[mateuszbasiak]

Together with @JKolodziejczyk and @apospieszny, we have been testing NanaZip as the final project for the Software Testing course at Jagiellonian University. Here is one of our results:

When the current path of NanaZip's explorer becomes unavailable (eg. the opened folder is deleted) the application freezes.

Reproduction steps

1. Create a new folder
2. Open it in NanaZip's explorer
3. Remove that folder in Windows manually

Expected result: After a short while application should stop trying to show the folder and instead show any available path (eg. root folder)

Real result: Application freezes and doesn't unfreeze

Version used: NanaZip 1.0 x64
