Describe the issue

NanaZip locks up when trying to update a password protected zip or 7z text file

Reproduction steps

Select a text file. Right click and Select Add to Archive. I have tried zip and 7z formats. Add an Encryption password. Click OK. Open the file in NanoZip and enter the password. Make an edit to the file. Save it. NanoZip says: File 'Test.txt' was modified. Do you want to update it in the archive? Click OK. The file name field turns gray and the file name disappears. NanoZip totally locks up. The process has to be killed to close it.

Expected behavior

Update the archive and stay alive.
