[Gambas-user] connot edit a class file in the IDE

[mikeB]

eGreetings Gambas folks,
I feel really stupid asking this question but after 2 hours
of pulling out what hair I have left = have decided to do so;-)

I started a new Gambas project and had been working on it for
several hours. All of a sudden it would not let me edit the class
code. Made sure that it was stopped running (Degug> Stop) and
also made sure that it was not "locked" (the lock icon).

Any clue what I need to do to get back at it?
Gambas 3.10.0
Linux Mint 18.3

Thanks for any/ all help,
mikeB
