Hello,

I will provide three things in this post:

1) Specs of PC etc.

2) The problem

---
Specs on PC: Windows 7 with all latest updates, two mIRC installations. One installation is a standard installation in standard directories. 2nd installation is installed in different directory and using the "Run as portable application" option.

Problem: Upon updating both installations of mIRC from 7.52 to 7.53, the installation installed with the option of "Run as portable application" no longer sends any message when using the /onotice or /omsg commands. These commands are used frequently by the scripts I wrote. None of the scripts were changed - merely an update to v 7.53 made the /onotice commands stop working. When I downgrade back to v 7.52, it works fine. The v 7.53 on the normal installation works fine too for /onotice - only the /onotice command on the "Run as portable application" installation fails on v 7.53, but downgrading that back to v 7.52 fixes the problem.
