Pushbutton sends app designer panel to the back.

I have an app with two buttons that use uigetfile to open a file, then the third processes them. When I push either of the first two buttons, it pushes the panel to the back. It looks like it has crashed. I have to click on tabs to get the panel back to the front to proceed. I have to process quite a few files. It seems there should be an easy solution, but it eludes me.

properties (Access = private)

RNETPath

RNETTable

KTMTable

end

% Callbacks that handle component events

methods (Access = private)

% Button pushed function: ReadRNETButton

function ReadRNETButtonPushed(app, event)

[RNETFilename, app.RNETPath]=uigetfile("*.csv");

% app.StatusEditField.Value='Read and Process Test Iads';

% Combine filename and path strings

RNETFileandPath=append(app.RNETPath,RNETFilename);

app.RNETTable = readtable(RNETFileandPath);

%

end

% Button pushed function: ReadKTMButton

function ReadKTMButtonPushed(app, event)

[KTMFilename, KTMPath]=uigetfile("*.csv");

%

% Combine filename and path strings

%

KTMFileandPath=append(KTMPath,KTMFilename);

app.KTMTable = readtable(KTMFileandPath);

end

The issue seems to be with how the UI is configured and not with these "ButtonPushed" callbacks. Can you share the app designer file so that I can look into this?

This is the export file from app designer.

Thanks for describing the problem.

This is a known issue (previous reports: 1, 2, and others).

This has been fixed in R2025a. Focus now returns to the app that called uigetfile after the dialog is closed. The fix is also available in the R2024a and R2024b beta releases only (not the R2024a and R2024b general releases).

[Stephen Marsden]

Can I access the beta release?

[Adam Danz]

Certainly.
