Thought I'd report a problem I occasionally have in winbox, in case anyone else has experienced it, and maybe log it as a bug?
Not always, but every now and then, when opening an existing Firewall rule to edit, I find it no longer responds to mouse clicks, and appears semi-frozen. It's quite frustrating.
I discovered a work around to be:
1. Minimise Winbox.
2. Unminimise Winbox.
3. Close the rule I had opened by the "X" (nothing else works).
4. Reopen the rule I was trying to edit, it will now let me edit it.
As I said, doesn't happen every time, but when you're doing a lot of configuration, trial and error... it can happen alot.
