I haven't logged into my account for awhile. However, I decided to send my XLM to an exchange to trade them in for something else. After trying 3 times I downloaded the latest version tried again several times and all of a sudden it allowed me to send 20XLM. So I decided the next day to send a larger amount but with no success. The send button will not activate. I have the latest version for Stargazer for Mac 1.7.0. Please advise what to do? Thanks Richard
