So i noticed a bug in Winbox version mentioned in subject of this thread. When i open up Winbox and go to IP->DNS then click on “Cache”. When i choose filters, if i select “Data” filter winbox will immediately crash. It will exit the app. Regardless of which router I’m connecting to (i have two mikrotiks in my home, both different model).
If i choose any other filter it will work fine.
1. Backup your Addresses from Winbox
2. Go to %APPDATA%\Mikrotik\Winbox and delete everything.
3. Remove the contents of the folder where you have your winbox.exe and download the latest from mikrotik.com
3. Restore your Addresses
4. Test
Tried to replicate your issue and I could not get Winbox to crash.
later edit:
It seems I was using Winbox 3.17 instead of 3.20
Tried with 3.20 and indeed, it crashed as the OP stated.
