Dan: That might work, but TheBlasphemer told me I could use GetCurrentProcess, and it works.
The plugin will now only exit the instance where you type it in, with /xexit and /xexitr.
/xexita has been added, which will close all instances. FYI, it uses msnlaunch.exe to do this, since imagine this:
app.exe launched 5 times, the first one is used to kill all instances.. it'll start by killing itself, thus nothing is going to kill the rest. That's what was happening with it in MSN Messenger, so I had to get msnlaunch.exe to perform the task
Pure_BY: As for the popups, they close as soon as MSN Messenger closes, so I'm not sure how I'd do that... :/
