I'm using Keil uVision4 version 4.54.0.0. When I check out a .cpp file from uVision4 IDE, I get the following message from Keil:
"Project file is read only. Saving is not possible!"
From Windows Explorer I see "Read-Only" attribute is not set on filename.uvproj. Also, filename.uvproj is checked out.
Why does keil display above message ?
