Help! Designer Is Only Selecting Background

[Mr. Sam]

See posted video.

All of the sudden, Designer won't let me double click to select any object, it will ONLY select the background. This is getting SO tedious when working with multiple objects. I have always been able double click (maybe more clicks) to select any object, even if it is grouped inside other objects... Click enough times, and the software will select it. About an hour ago; this stopped happening and I have no idea why. I click 1000 times and it will never select the object, only the background. I can click on the layer to adjust, but if I accidently click off, I'm back to the background and have to scroll to find the object I was on... This is maddening!

Can anyone help me understand why Designer isn't allowing me to click to select an object.

[Mr. Sam]

Update to the issue. I can select the parent object, but can not multi click objects nested under any parent object to select them. This is becoming SO time consuming.

Have you tried holding the ctrl key down while you click on the stroke or fill?

[Mr. Sam]

@firstdefence, thank you for your reply. I am aware of the ctrl left click to select an object, but that wasn't working. 

Strangest thing... This was taking so much time trying to find the correct ellipse to fill, that I ended up shutting down my PC for a day and taking a brake. Now, I'm back at it, and for some reason the standard double click on the ellipse/object works. There must have been some sort of bug in the program; but now we're back in business! Thanks again.
