I've just had two occurrences of windows 7 stalling an execution until I hit enter on the command prompt/powershell. Afterward execution seems to continue as expected.
First was an batch file of copy commands like
copy //host/file2010-1*xml localfolder/01/ copy //host/file 2010-2*xml localfolder/02/
One file seemed to be taking ages. I checked the folder and it was complete, hit enter and suddenly it burst back into life to get the rest.
Second is a java program (an ETL job) in powershell which paused as it was about to output SQL duplicate key warnings. I cannot confirm if actual execution stalled but I suspect not. I have just repeated this one as I type.
Also my more experienced colleague has seen the same thing with .net programs he has written.
How can I avoid this? What am I missing? Does Windows get lonely and need a gentle push?
