Forums Scripts & Popups dec -z won't count in seconds

Quick example you can run directly from the editbox (typing area) in mIRC: /set -sz %iirevar 10

The /url -a causing the browser to open a new window rather than a new tab might be the fault of the browser's handling of this task rather than a fault of mIRC. What browser do you use?

Oh, I didn't notice, but you should also remove the var %y_t (and the related if statement) from your code, else the variable will be made local and deleted as soon as the script finishes.
