Accidentally? :astonished_face:

It has become rc again? :laughing: Better return it to beta branch.

5

Every new version brings new hope—I'm going to give it a try, use it, and test it.

6

How many posts about the same. ....

7

You can post something better? Do it. I've posted 50+ detailed issues, the post was removed. Now I can only laugh about this :poop:

8

Still the same issue for me with missing entries in tables on Windows11 on ARM :pensive_face:

9

Please add a setting to disable checking for Winbox updates:

APP,UPDATE,ERR: version fetch error "Host unreachable"

Apparently there is still work todo w.r.t. fields:

!!! TODO u32_array "Pairwise Ciphers" "WiFi"
!!! TODO u32_array "RSN AKMS" "WiFi"

This says "WiFi" but that router is actually using "wireless".

Please implement some commandline option to connect to an entry from the Addressbook immediately. Now, when started as "Winbox devicename" the devicelist appears with that devicename already selected, but it would be nice (e.g. with a --connect option) when it could immediately connect using the stored username, password and workspace, so shortcuts can be made to connect to a device.

10

Please add a setting so you can change like the RouterOS update with Stable and Develop versions.

The immediate update function works great with my Arch Linux install, and will be more great if you can change what channel you want to update.

11

still the same problem with the sometimes scattered arrangement of windows !

12

aha!

Some people will dislike. Can this be enabled/disabled in settings? Haven't checked the new rc yet.

13

It doesn't fully lock up anymore, but it's still lagging. I don't know why this needs to be an issue in 2026.

14

Hi,

Could you share a few more details so we can better understand what's happening?

  1. What OS are you using?
  2. What is your hardware specification?
  3. Which table lags?
  4. Are you scrolling with mouse/touchpad?
15

No issues with scrolling on my Linux system.... What I do notice is that a large table (e.g. the log window) that is permanently open causes continuous redraws even when there is no change in the content. Maybe that causes performance problems for some people? I notice it because I have a remote system with some Winbox sessions open that I access via VNC and when I have the Winbox window in view there is like 500KB/s of network traffic, that isn't there on when another window (e.g. Firefox) is on screen.

  • the state (column sizes, sort order, etc) of windows that are not directly linked to the menus is not saved. would it be possible to have that? (e.g. wifi scanner, torch, ...)
  • it would be nice to have user-definable buttons in the top bar that run a script when clicked (or maybe just any command)
  • the font selector could be improved, just like the file selector has been improved in the past. I mean: have some proper font selector from the underlying system libraries instead of the plain dropdown box

  1. Windows 11.
  2. Intel Core i5-13500, 32 GB RAM, GeForce GT 1030.
  3. Tested interface, firewall filter and log tables.
  4. Mouse wheel scroll.
18

Thanks!

Some additional questions:

  1. Does it lag when scrolling is done with scrollbar?
  2. Does it lag when scrolling longer comboboxes? e.g. System -> Clock -> Time Zone Name
19
  • Manually dragging the scrollbar seems to work fine.
  • Time zone combo box often gets stuck for a moment when starting to scroll, but seems fine mid scroll, unlike tables.
20

Ok, if using scrollbar doesn't lag, then problem most probably is with mouse wheel scrolling logic. We will refactor it in version 4.3, hopefully this will be fixed.
