Jonas,

Yep - you're quite right.  There is a bug in the EGW_LoadData routine 
which means that the current cell is not reset to something sensible 
when the dataset is replaced.  

I will fix this in the next release, but in the meantime there is a
simple workaround that you can use (see code following - the fix is in 
the DepClearPB_onClick routine).

HTH,

Phil
