AdiIRC

Actually, the impression I am having is: AdiIRC is confusing the "tab id" with a file

Forget the first example.

Sorry

The first example works well
<file.jpg> must come first (with a comma included), but i also tested:

dialog tabtest {
size -1 -1 400 400
tab "test",1, 10 10 380 300
tab "another tab",2
icon 3, 10 10 120 100, tab2
}

on 1:dialog:tabtest:init:0:{
did -g $dname 3 <file.jpg>
}

There must also be a comma after the filename, also you should probably test in mIRC before reporting scripting bugs, unless the script uses AdiIRC specific features.

Not sure right now, but I guess the second example is a valid bug.

If you test the second example in mIRC you would see "/dialog: 'tabtest' error loading icon 'tab2'" a valid icon in the first parameter is required.
