I have version 6.12 of mirc, and if i use /server -m and then close that second server window, when i open a url in the first server window, mirc stops responding, "Causes a problem and needs to be shut down"... anyone else got this problem??

I cant reproduce it, reply with the exact methods you take to do this, including what windows you type the commands in.
(and also make sure that your scripts are unloaded and no dlls are active, as they can be the source of the problem)

if you have all of your IE's shutdown.
and youo try to click on url in the mirc. It will freeze your mirc.

need a check to see if IE is running.

I have same problem

you are not only one.
