WinBox problem after upgrading to v6.48

Is anyone experiencing problems after upgrading to v6.48 when trying to add a new policy @ IP/IPsec?

When clinking on the + sign to add a new policy , WinBox shuts down !

Tried it on 2 different routers and does exactly that…

UPDATE: After downgrading to v6.46.8 WinBox works fine

Which version of WinBox? Have you tried clearing Cache (via connection dialog)?

WinBox v. is 3.19

I cleared cache via winbox/tools but problem persists … how do I do it via connection dialog?

UPDATE: WinBox version 3.27 works with v6.48

That was going to be my guess - old version of WinBox.
Glad you got it resolved.
