It does that that to me also when I click "save as", input a filename it replaces my users.mrc file and goes to the users tab.
I also have another script that somehow seems to move itself from the remotes to the channel popups and erases the channel popups I previously had. That I haven't caught in the process of doing so I don't know what triggers it yet. When it does this I see much of the script as a channel popup menu when i right click in a channel, tho neither the script or popus work any longer.
Those who live by the sword get shot by those who don't.
