well I didn't know where to place... and since 1.4.0-beta5 was the tested version... and not available as an option, I tried the closest one, so:

when running any GameScript available, since they send info to GSGoal, only the 1st company gets "Goal list" aka "Goal GUI" window updated correctly.
I guess is a Draw issue, because desired info is shown correctly immediatly when other companies resize "Goal list" window...

I'm currently looking at http://nogo.openttd.org/api/trunk/index.html and since works very good for 1st company... and good (when window resized) to other companies... in ALL GS's available... that's why my report ^^

well, in simple words... and to test it:
- start an OpenTTD 1.4.0-beta5 server, with an existen GS that uses/creates new entries in GSGoal
- join server using different connections (not really needed... but just in case... with different player name too...)
- open "Goal list" 1st company created... and for all others too... well, and open "Goal list" for Spectators... if you got another different internet connection...

If needed an online server to test this issue (among the bananas GS's), just tell me!
if I made some english error, save it... I care more with OpenTTD!

best regards

Reported version: 1.4.0-beta4
