when including "inputdlg" in a simple script I recieve the following error:
Error using matlab.graphics.Graphics/set
Unrecognized property Units for class AnnotationPane.
Error in inputdlg (line 340)
set(findall(InputFig),'Units','normalized','HandleVisibility','callback');
the dialog box opens but the 'ok' and 'cancel' buttons can't be pressed and the only option is to close the window.
I checked that it is not a syntax problem by copying the inputdlg example code from Mathworks, https://www.mathworks.com/help/matlab/ref/inputdlg.html

Please post a piece of code, which reproduces the problem.
Did you shadow a builtin function? This can happen when folders with user-defined functions are stored in the path before Matlab's toolboxes.

User the debugger to find out more details. Type in in the command window:
dbstop if caught error
Now run the code again and check, which line is failing and the values of the used variables.

Thanks.
Here's a simple script:
%Testing input dlg error:
prompt = {'Enter matrix size:','Enter colormap name:'};
dlgtitle = 'Input';
dims = [1 35];
definput = {'20','hsv'};
answer = inputdlg(prompt,dlgtitle,dims,definput);
and here is what I get after running the debugger:
Caught-error breakpoint was hit in helpviewFactory>helpviewFactory.get_location_for_topic at line 60. The error was:
Error using helpUtils.csh.helpviewFactory/get_location_for_topic (line 60)
Java exception occurred:
com.mathworks.help.helpui.HelpTopicException: <html><body>Topic error_hg_InvalidProperty not found for product MATLAB.</body></html>
at com.mathworks.help.helpui.DocSetItemTopicCshRetriever.getCshResultForTopic(DocSetItemTopicCshRetriever.java:63)

at com.mathworks.help.helpui.TopicUrlRetriever.getLocationForTopic(TopicUrlRetriever.java:30)
does that make any sense to you? Thanks again...
