Cannot get RTX to start tasks on reset

Hi, I am using the evaluation / startup kit for the MCBSTM32 (Keil uVision3 V3.55a). I am able to rebuild and run the sample application 'STLIB_RTX_Blinky' found in the keil samples (C:\Keil\ARM\Boards\Keil\MCBSTM32\STLIB_RTX_Blinky). However, when I try to create a new project using RTX I cannot get the application to start any of the tasks I created. I can see (via the debugger) that I call/execute the os_sys_init(initmytasks) function but I never see 'initmytasks()' get run.

I have done file comparisons for my RTX config, startup HW config, etc between my app and the 'STLIB_RTX_Blinky' and can see no real differences that would seem to prevent starting the tasks. If I break while the app is running I am always in the 'os_idle_demon'.

Can any on supply any input as to what I may be missing or could check to troubleshoot this further ?

Thanks in advance

Burt
