I'm using IntelliJ IDEA on a Ubuntu box and it works quite well....despite one extremely annoying thing:
If I have to open up several IDEA instances, e.g. to look into an example project (1st instance), digg inside the code of a prototype (2nd instance ) and create a new project inside the 3rd instance, the window icons on the taskbar go missing after a while and thus i cannot quickly switch to the project i want to see (using alt+tab ist not very efficient for me as all idea instances have, of cource, the same icon). Switching to the "missing" instance with alt+tab and minimizing it brings it back to the taskbar for a little while. this whole behavior is annoying ;-)
does anyone have the same problem or is there - even better - a know solution for this?
