Description
My computer is a Lenovo thinkpad x230. Host OS is Fedora 20. Guest OS is 64bit Windows 7 Enterprise SP1.
I can reproduce this bug in 4.3.20_96996_fedora18-1 from the virtualbox yum repo, and the test build 97569.
Attached is the latest log from the last time I reproduced the bug, these are also the events I describe in this report.
- Start guest VM.
- Open notepad or any input field to test keyboard
- Type some words.
- Press right Ctrl to release keyboard from guest
- Press alt+tab to switch host OS program, do not release alt
- Switch back to guest VM with alt+shift+tab
- Type some words in notepad
Expected result: Letters from a-z and numbers from 0-9 typed out on screen.
Result: The menus activate randomly in notepad, no words are typed. In other programs like Putty I see strange characters being input, sometimes spaces, sometimes returns, never the expected character. In the Windows desktop random functions might be activated, or nothing will happen at all depending on what keys I press from a-z and 0-9 on the keyboard.
Workaround: Press left ctrl+alt once and typing is restored.
