Specs:  Acer Aspire 5517; Windows 7 HP, X64, SP1;  
The Webcam, built-in to the laptop, has worked well until recently.  Now, the Acer-provided application (Acer/SuYin v. 5.0.9.1 application) can not find the Webcam.  I did make sure that the Global Settings of Flash (Adobe) were OK, or at least normal, as I remember them. 
Any suggestions as to the direction I should pursue?  The driver says it is operating properly.
