I am working with Spark now for around 48 working hours. During this time I often had the problem that the Spark would not receive a flash from the Webinterface (SparkIDE). The LED shows breathing cyan but does not do anything. Sometimes it shows a blinking green for one or two minutes, then goes back to breathing cyan. I can torture the Flash button, but nothing happens. The only solution is a factory reset which I did like 30 times in the past 24 hours.
Is this normal behaviour? Or is it my fault? Any ideas or suggestions? It is a pain in the ass if I cant flash the Spark reliably from the SparkIDE.
