I am using version of MDK-ARM 4.12 and ST-Link programmer with latest firmware (Feb. 2010).
As also other users have noticed, it is not possible to download code to device with single click. Neither is possible to select JTAG / SWD communication protocol. But debugger works.
Is there any special settings or it is a software bug?
Tested with latest and older IDE, with and without license, on different machines. All that is common is WinXP.
Here are other users with the same problem:
