Hello,
Occasionally, uv4 enters a prolonged delay status after linkage (of us to 15 seconds) on my PC during which the entire application is blocked. The only solution I know to deal with this is to erase the following registry keys:
HKEY_CURRENT_USER\Software\Keil\µVision4
Have you encountered this before?
ARe you running your PC at more than 70 degrees?
