Command Window gone crazy ( scrolls on it's own )

My command window has lost its mind. It behaves normally but after I type some commands and get some output, the command window automatically scrolls up until I can't see what I just typed. The only way out is to type clc. But even that doesn't completely help.I tried typing "home" but that seems to have made things worse (I think it's now scrolling to a different position... or something).
How can I get back to normal? I checked all the Matlab preferences and... nuttin!
Help?

please help!

Have you tried Matlab--Preferences--Command Window and set the Number of lines in command window scroll buffer larger? I tried to change it from 5000 to 10000, and now the issue seems to be solved.

I have the same issue on my Macbook Pro. Changing the buffer size of the command window did not make a difference. I assume it is still an unresolved problem?

Had to restart Matlab. I think it's OK now.... weird!

Same issue here. It happens from time to time apparently without any cause. Restarting is the only solution, however this is very inconvenient! Is there any patch to solve this issue? Thanks

I have also had this problem for awhile, maybe since R2013? I now run R2014b and it is still an issue once and awhile. I have to restart Matlab to get rid of it. I have not been able to figure out what causes it. I'm surprised there are not more comments about it since it is so annoying. Perhaps it is related to running this version of Matlab on Mac OS 10.10x?

Not sure if there is a permanent fix yet, but a fast solution is to clear the command window by (e.g., Command-k on Mac).

I can add to this that it happens with Matlab 2009b as well, however, under Mac OS X Yosemite. I have not ever had that issue with my older system. Clear screen may help with the command line, but it affects the editor in my case. Restarting Matlab helps. Java issue? My colleague (scrolling of the command window, Yosemite) noticed, that Matlab tends to crash altogether soon after the scrolling issue starts.

R2009b for OS-X was more based on X11, and less Java based. You would have needed to install XQuartz to run R2009b under Yosemite. You are getting near the limit of how old a MATLAB version you can use and run under Yosemite.

The window is scrolling back to the position where your cursor is. Have the same issue in El Capitan. Could not find a way to turn it off.

I'll add a bump/complaint. I've also been having this issue from versions 2015B to 17A at least, maybe earlier too. I mainly use a Macbook Pro (constantly up-to-date OS over the past several years, with the ongoing problem...) but haven't seen this on Windows machines, though I haven't used them enough to be sure.
Restarting MatLab does fix it, but that's a workaround and not a solution...

I recommend you contact Technical Support and work with them to determine the circumstances under which this behavior occurs.

Answer by Michael Rollins on 5 Jun 2017

I experience the same issue, running MATLAB 2017A on macOS Sierra (10.12.5). Clearing the command line code (clc) does the trick in the short term.
To add to the depth of the issue, automated scrolling has also occurred in my script window, scrolling to a particular range of code lines even if I move the cursor or change the focus to another open script. For those in the same boat, closing and reopening the script was enough to fix it for now.
I'm sure this is a low priority bug, as it merely causes an inconvenience, but I sure hope it gets addressed soon!

Answer by Xiaochun Xu on 7 Jun 2017

I had the same problem, running MATLAB 2015a on Yosemite (10.10.5). Usually it happens when the RAM is busy (if I quit some apps, it might recover). Closing Matlab did help. I tried clc, it does not work for me. I realized today that if I close the tab of script, it helps as well. I guess this is the most convenient way without losing all the data.

I have the same problem (MATLAB R2017a, OSX 10.12.6). Had this issue time to time and the only fix is to restart MATLAB.
