[Gambas-user] TextBox and CR

[Ron]

If I mis understood the issue please ignore me but...

I have seen occasions in my Gambas project where:

IF this AND that THEN

didn't always do what it was suppose to do.

I had to do:

IF this AND IF that THEN

Most of the times the first one worked ok, but not always...

Ron_2nd.
