Propblems with plots after installing Matlab 2024a

After installing Matlab 2024a I have encountered following problem

I create any plot command, e.g.:

>> t = -3:0.1:3;

>> y = t.^2;

>> figure, plot(t,y)

After moving the mouse pointer over the axes in the figure, I recieve th following massage:

Warning: Error occurred while executing the listener callback for event WindowMouseMotion defined for class matlab.ui.Figure:

Similar problem appears when i try e.g. copy the figure into the clipboard:

Can you tell me what is wrong?

I use Windows 10 Enterprise LTSC, 64-bit, version 1809, build 17763.5696

Thank you for the answer, with best regards,

Roman Vitek.

You probably need to reinstall MATLAB.

[Roman Vitek]

Thank you very much for your advice. I tried to reinstall Matlab, but without any positive effect. I am still obtaining many error messages, obviously connected with the motion of the mouse pointer over the axes area.

I think that this problem is probably caused by the version of Windows. According to the release notes of the Matlab R2024a the minimum version of Windows 10 is 21H2. My version is 1903. I will have to reinstall the Windows very likely.

At any rate thank you for your help. Regards, Roman.

Hi,

I had the same problem than Roman, but in a Mac, and after deleting Matlab and reinstalling it, this error desapears. Thanks Walter

This is NOT a solution!

I get the same error in Ubuntu with the latest 2024 update.

[geofo]

Problem solved for me: I executed the following commands at the Matlab prompt, which solved the problem:

> restoredefaultpath

> rehash toolboxcache

> savepath

Works perfect, thanks!
