emonGLCD V1.4 - startup/boot problems?


Here is another oddity which I'm not sure how to tackle.... I have my nice new V1.4 emonGLCD up and running well (apart from the screen issue) - the GLCD_tester firmware happily running fine for ages.  When I run the emonGLCD_HEM firmware, again all works fine..... the first time.  If I power down and restart the board goes straight to some form of crash - no screen action and both LEDs red.  No matter what I try nothing can persuade a start, the only option is to load the GLCD_tester firmware and all is good again.... repeats the same each time I try.

Very odd - anyone else finding the same?
