[GNC] opening accounts bug

[Ira Fuchs]

When in the Accounts tab, if I type any of the letters in an account name, the first matching account is highlighted. In order to open this account, it used to be possible to merely hit Return. It is now necessary to double-click TWICE (4 clicks) to open the account. It would be very nice if it could open with just a return nbut if that is not possible, then at least going back to 1 double click would be an improvement. This behavior is on a Mac running Mojave with GC v4.0.
