Failed to clear temp storage

Getting the following error message in my debug window console: "Failed to clear temp storage: It was determined that certain files are unsafe for access within a Web application, or that too many calls are being made on file resources. SecurityError"
I am running the VS2013 simulator and can't find a particular place or time when it happens.
Any thoughts on how I can determine the cause of this error?
Thx

Hi Cecil,

This is the first time we receive such error report for the AppBuilder Simulator. Performing a search about the exact exception message, I found the following article. It makes me think that if you clear the Simulator's cache, the faulty behavior should correct itself. Could you please close any opened VS instances and then, delete the whole %localappdata%\Telerik\BlackDragon\Cache folder on your machine and try again?

Please, let me know if the issue is still present after that.
