Dear Sigma, I'm not keeping the DP1 Merrill.

So, errr ... you are waiting because you are impatient? Allow me to smile a bit 

Anyways, with 5.4.1, the CA-correction now finally lets me chose the "lens profile" option, greatly superior to manual correction. So I have little left to complain about (except the wet grey and dark weather, a feature not attributable to SPP I believe).

Neil, if your time is that valuable, save some of it, transform it to a faster processor and/or more memory on your developing computer. Configuring your anti-virus to leave X3F-files and SPP alone, may also help drastically.
