This has worked fine in the past but today if I open a variable from the workspace to the variable editor I receive "an unexpected error has occurred" rather than the values of the variable. It appears to happen after I change my current directory. So at startup in the C:\users\Documents\Matlab, I can do A=1 in the command window and then open A from the Workspace and see "1" in the variable editor. If I switch to a different directory (same ones I have used for months) I get the error. I have seen this question asked before but no one has answered yet.

Which M-files and DLLs are contained in this folder? It seems like one of these files conflicts with the method used for the workspace browser.

There are various m files in these folders. The same ones that have been there and no problems have been seen in the past. Edited- This was not quite true this folder contained an m file that appeared to conflict with the variable editor. Renaming/removing this file solved the problem. Thanks!

I had the same issue. Although I did not find the root of the problem, the following worked for me. Reset your matlab path to the default values & add those locations that you need again. Afterwards, the conflict with the openvar() function (performing the actual functionality of the variable editor) was no longer there.
