Ah, thanks Lanux! I saw the thread but didn't remember that FarrAltTab was also involved... That's too bad. I tend to use it a lot. I guess I'll have to chose between one of both options, in the mean time.
Just in case, here's the related post from the other thread :
pursuant to my thread here, i've found out that another plugin is causing the same problem - FarrAltTab. enabling this plugin also breaks the following:
1. 'Ctrl+Alt+Enter' hotkey to open all search results.
2. '/stayopen' keyword assigned to aliases.
3. 'Launch and stay open' - either via context-menu or hotkey.
BTW, the 'Ctrl+Alt+Enter' hotkey to open all search results still worked for me, even with the FarrAltTab plugin enabled... weird.
