I have come up with a very strange problem. I had a GUI+the code to communicate to a serial device and plotting the data on screen. Every thing was perfectly working till yesterday, today when I resumed my work, my GUI buttons,text inputs etc nothing work, I checked the search path if my directory is missing from the search path but everything seem to be okay.
In order to verify that the problem is not with my GUI and code, I created completely new test GUI with a single button in it such that when the button is pressed (callback function) it should display a message box i.e.
function pushbutton1_Callback(hObject, eventdata, handles)
but the GUI is not responding to its corresponding code. It looks like there is a permanent break between the GUI interface and my code.
Any idea ?
