The full message says:
"The Viewer module could not connect to the Run-Time. This could happen if the Run-Time has unexpectedly stopped due to lack of memory or some other internal problem."
I've been expiriencing this situation for a while. The problem is that it is imposible to know when it is going to happen and the message that is given doesn't clarify anything about the specifics that cause this error.
After this error, I have to stop the runtime, the Studio if it is running, and start everything again. It happens about twice a week.
Any ideas on how to solve this?
