as I wrote above, (and highlighted in bold) that setting is not saved in NVM and you have to do that every time you run the the software. I don't have SDR# running constantly and since it does crash from time to time, it's not really my favorite feature.
Interesting, that is one setting I change every time I unzip a new version of SDR# and I never have to go back to it ... until the next version is released.
Just for grins, where do you have the sdrsharp-x86 directory located?
