I Give Up, Yosemite Destined For The Trash Bin!
I tried various fixes to abate the bug in the "Finder" (see below) to no avail. While ignoring the other less intrusive and annoying bugs. Today, I finally gave up and erased the Partition and will install once again on top of my Mavericks Daily Machine when Apple releases the "final version" Final...? and attempt to use Yosemite one more time. This will be the first time from Leopard to Mavericks, that I will be installing a new OS X onto a test partition for fear of rendering my Machine unusable! Thanks, Apple!
I am forced to drag and reset size and position of the Finder Window, resize Side Bar and resize Home Folders (I was able to stop, having to resize Folders after selecting "Use as Default" in "Show View Options") after every restart of the Machine and at various other times while using the Machine. This is extremely disruptive, time consuming and frustrating. There is no acceptable excuse for this not being corrected in Beta 5. The Finder and System Preferences are the heart of OS X and yet they have allowed this bug and many others too continue through 5 beta releases. Disappointed is a gross understatement.
For Apple's lack of concern, respect and appreciation for the Yosemite Beta OS X and its testers (Apple Customers Working For Free) with their feedback, is disgusting!
