Hi bault10
The problem may be caused by IDE install, workspace setting, project setting. driver, windows application confliction or so on.
I suggest you creating a new project under a new workspace to test again. If problem persists,
Please download and install the latest CW11.1
you use very old CW version. version 10.2 is slower than 11.x .
CW11.1 improve the performance of old versions.
Hope this helps,
Jun Zhang
