When trying to do a $style for my @window, my variable contained a : (semi-colon), and this seem to cause issues, as seen with...
Code:
menu @testwin {
  $iif(%some:var == 1,$style(1)) Set:set %some:var 1
}

Just /window @testwin and try and rightclick to bring up the menu. I did further tests and the : in the final bit (Set:set %some:var 1) works fine, it's the : inside the $iif.

IMO this shouldn't affect the popup at all.. Just wondering if anyone else can replicate this. I'm using 6.12.

You won't like it when I get angry.
