I have that problem here with fldigi 3.10, where fldigi is not properly 
when jpskmail is started. 
I have solved it by switching AFC off.

You can checck if the initialisation is ok by clicking in the waterfall at a 
random spot.
When fldigi is properly initialized the qrg should immediately return to the 
sweet spot.
That does not happen with the copy I have here, it is o.k. on my desktop at 

We will have to take a closer look at this (but after my holidays :). 
Maybe someone can take a look at the fldigi source code...
