raffav - In most cases, updated software is released before the CVE is published (https://nvd.nist.gov/vuln/detail/CVE-2020-5720)
hngjared, sid5632, null31, hel, brotherdust, proximus - We will resolve this problem in upcoming RouterOS releases. Winbox 3.20 is available here - https://download.mikrotik.com/routeros/winbox/3.20/winbox.exe (winbox64.exe for 64bit version)
null31 - Can you reproduce this crash constantly? What exactly do you do? If I click with the mouse right button on a file and choose “Download” option, then WinBox works just fine for me
Sob, MichalPospichal - We will change default line height in upcoming WinBox releases
