Excerpt from bug description:
"Not sure whether it is stably reproducible but here is my experience: 1. Upgraded Skype with latest version (22.214.171.1243 at that moment) on my Android 2.2. Samsung Intercept 2. Signed in 3. Wanted to finish working with app by killing that process: - tried to kill in ES task manager - app was shown as running (and it was really running) - tried to kill in Android task manager (did not show that Skype is running!!! while it was running and I can switch to that window)
The last step - force stop and cleanup memory through ES Task manager (advanced but ugly approach). Only that helped. though memory was still leaking. How Android could me missed handler of really running pretty big and UI app? How their task manger is implemented then?"
