I live mostly in the Mac world and you seem to be having an issue with a PC (Windows) but may I suggest you find and trash the setting/preference file/folder for Windy, if there is one, hidden deep somewhere in your computer. You may be able to find it in your browsers application support folder. Trash the preferences and start over. I have had similar things happen using my Mac especially with Firefox but with other software and find clearing out the old prefs/settings and starting over can do the trick.
