I run two copies of mirc, both in seperate folders and neither reading anything from the others files, and have yet to have an issue with it.
I run 1024 mb ram, 3ghz pentium 4, and mirc.exe is taking up anywhere from 30-40% of the processor, each. This is only recent, and I don't think it's my windows install going coruppt; There's serious system lag, and I did a reinstall of both mirc and windows to make sure.
One of the copies is a bot so I checked if I'd somehow started a loop, timer, etc automation I shouldn't off and it all works out, same with my other instance(the non-bot one).
Anyone have any ideas? All help greatly apprciated.
