You must not use 'LINE INPUT #Process, Var' to read a process output in
Process_Read. You must use 'READ #Process, Var, -MaxLength', add 'Var' to a
'Buffer', and extract lines from that 'Buffer'.
Without a full project to test, I cannot say more at the moment.
Note that Gambas 3 is more clever than Gambas 2 for that kind of situation.

CTRL+V works perfectly there. Do you have more details?
