title: Unable to use F5 to step into function while debugging on Eclipse
body: <p>Sometimes (about 50% of the times) , while debugging an Android app, in order to step into a function , I use F5 (F6 is for going over it) yet it doesn't do anything</p>
  
  <p>Sometimes, none of the regular debugging keys work (F5,F6,F7,F8, maybe other that i don't know about too). </p>
  
  <p>Currently, the only way to overcome this is to choose the current thread from the "Debug" view (that shows the current stack of each thread) and then press on F5 . When the situation is even worse (unable to use the content assist, for example), I restart eclipse.</p>
  
  <p>Speaking of threads, I've noticed that if I have multiple threads running, sometimes when I try to go further, it goes to another thread and this is annoying as I lose the concentration I had on the current thread. I know it does make some sense, but it's really annoying especially if I've taken into account that there are multiple threads.</p>
  
  <p>Why do those things occur, and how can I fix them?</p>
  
  <p>Note: I have the latest version of both Eclipse, ADT and the Android SDK . the problem occurs on both devices and emulators.</p>
