	I was trying to debug a sketch. The expressions window would not appear. I added a Serial.begin(115200) to the sketch setup and now it is working. Is it supposed to be that way?

	No, please send the project_name.cpp from the temp build folder and the output requested above.

	Try updating Visual Micro to see if that makes a difference your release is from last year.

	All versions: There was release info that appeared in an output window after startup when the March version was released Visual Studio should show a flag in the top of the IDE when an update is available. Which ide are you using?
