yes, Ive been using mirc 6.03 under wine lately (yes it runs perfectly) well, theres a couple of niggles that would improve usability
Right mouse on the systray works, you get all the options..but an option to minimise to the systray (forcably) because the option to minimise in this case is controlled by the X11 Window manager, so minimising wont move it to the systray. So yeah, just an option to minimise on-right-mouse systray would be very handy.
the systray icon of mIRC, is the background transparient? because its showing the "windows grey box" around the mIRC systray icon. Say a transparient .png or .gif would be needed.
