Merry Christmas everyone,

Thanks Laurent for the update of iziBasic and speedy correction of the ABOUTBOX bug
(and thanks for the Christmas gift too).

I have, however, discovered another problem with the ABOUTBOX beginning with V. 3.1.

I thought the problem was my coding until I discovered that it worked right in programs compiled with v3.0. With programs compiled with v. 3.1 and 3.2, if the ABOUTBOX is brought up during a WAITEVENT when you click on "Ok" to exit the ABOUTBOX you are taken out of the program completely.

I have tried trapping it but that caused the program to lock up. Perhaps you can instruct me on how to trap it.

Thanks,
Douglas

 Hello Douglas,

Don't thank me too much when, by solving a bug, I bring another one to you!

OK, I will look after this strange thing. Maybe try using DOEVENTS for the time being...

Cheers

 Hello Douglas,

To figure out where the trouble was, I wrote and executed this quick program:
' Test.ibas
{CREATORID "TEST"}
{VERSION "1.0"}

CONST A$­­="Hello world"
ABOUTBOX A$­­
BEGIN
  REPEAT
    E=WAITEVENT
    PRINT E USING 0
  UNTIL E=-1
END


What I discovered is that WAITEVENT returns with a 0 no event value put in E when the user pops up the ABOUTBOX. This was not expected (WAITEVENT is supposed to return no 0 value event).
I found no other trouble.
So, I guess that your program exists because of your own coding...

I fixed this non blocking bug by having WAITEVENT (and DOEVENTS) returns with a 1002 event value, for information back to the program telling that the ABOUTBOX was displayed to the end user.

As this is not a blocking bug, I will not release a public version for it. I will wait to have a few other fixes to release one... and maybe, by that time, will it be version 4 with lots of improvements

Cheers
