Matlab Freezes when Double Clicking to Open M Files

Hi, I can't seem to figure out what's wrong with my MATLAB install.

When I'm working in MATLAB, I cannot double-click on any m-files or such in the "current folder" pane and get them to open in the editor. This has always worked before, but for the past 6 months this problem has been occuring. When I double-click on a file in the folder pane, MATLAB just sits there, never opens the double-clicked file, and ceases to respond to any other commands. The only solution is to restart the program. So, if I want to open a file in editor, I have to use edit xxxxx at the command line.

I have reinstalled MATLAB as a fresh install and still the problem persists.

Hi John,

The issue you are facing is encountered by various users. Please try the following workarounds:

1. Comment out lines associated with video files:

• Type "edit finfo.m" in the MATLAB command line.
• Comment out the following line:

[ext, description] = getVideoInfo(filename,ext);

The above steps have been mentioned in the following MATLAB Answer: https://www.mathworks.com/matlabcentral/answers/89422

2. Use the MATLAB file association shortcut fix:

• Downlaod the zip file: https://www.mathworks.com/matlabcentral/fileexchange/51165
• Extract it and run matlab script named associateFiles.m in Matlab. By running this script, a new file with extension *.reg will be generated in same folder.
• Go to folder and double click on this *.reg file. Regisrty will be updated.
• Now restart Matlab.

As I said before, I have the same problem, with the addition that even from the command line "edit xxxx.m" hangs for about twenty seconds. I realised that some network drives mapped on my PC were offline. In my case it was a local NAS that had switched off. By reactivating the NAS everything seems to be working normally. Note that I was not using files on the NAS nor does my path contain anything on that NAS
