'No target connected' - again

I have been using the STM32F4 Discovery board for a short time with no problems (using SWD via mini-USB) when I suddenly got the 'No Target Connected' error. Reading the forum I tried the fix of BOOT0 high and BOOT1 low during power-up. I am using Keil uVision4 and pressing 'LOAD' I get :

Load "...myprog.AXF"
Erase Done.
Programming Done
Verify OK

If I now disconnect BOOT0 from Vdd the code and press the reset button the code runs as you would expect.

My problem is I have to repeat the  power down - BOOT0 to Vdd - power up - load - disconnect BOOT0 - reset sequence every time.

How to I return the board to the state it was in before I messed it up ?
