context menu dissappears before the cursor reaches any of its items

[Alexey Baskinov]

The release is 11.04. The package version is 5.0+build1+nobinonly-0ubuntu0.11.04.2. I expected the context menu to stay in place while I was selecting one of its items. Instead the menu disappeared before the cursor reached it. The following extra add-ons were installed and activated: «Context Search 0.4.6», «Firebug 1.3.7», «TextMarker! 0.3.4», «Типограф 1.17».
