Hey all, I haven't been able to detect what causes that bug but sometimes pressing the mirc button on the taskbar to minimize the mIRC window just doesn't work, it does nothing.
Once in that state, i can press it as many times as I try, it will _never_ minimize the window.
To make it work again, i right-click the tray button and select minimize in the context menu then the taskbar button minimize/restore function start working again by clicking on it.
I am using mIRC 6.21 on XP HOME SP2 and all patches to this date.
The bug isn't new to this build. It has behaved that way as far as I can remember using mirc which is a couple of years.
If you need further infos on my system/setup to debug this, just let me know.
