I had no trouble with Galaxy for a couple months but now of 1.2.37 I try and get games and go to do some house work and when I come back it is a white void(meaning frequently GOG tries to refesh everything visually a does it so many times over the hours I am connected it eventually fails at it) GOG needs to quit refeshing the screen!!!. no game list, no library screen and no way out of it except to reboot computer. I leave and come back and sure,enough again a white void, nothing except the bar at the top of the screen with "GOG Galxaxy 1.2.37 and a minimize window box and close "X" this has haappeend since I attempted to download Pillars of Eternity, Tides of Numenera, and Koma but also other games I cant' recall. my connection speed is between 1.6-6.1 MB/s
PC
Intel Core i7 4770K CPU clocked normally 3.50 GHZ no OC on my rig
RAM 32 GB
OS Windows 10 Pro 64 bit
running no security softrware except for Windows Defender nothing interfering there.
SSD OS drive Samsung using Samsung Magician and "Rapid Mode"
SSD/HD hybrid Seagate D:(game) drive
both have TRIM enabled.
onboard ethernet Mobo is Asus Maximus VI Extreme device ehternet using driver by Microsoft(because I don't trust the Intel download "tool" for Intel with its odd residential entry) I use MS driver 4/5/2016 12.15.22.6(MS for intel as provided by Windows 10 update)

wanted to send screen shots but it won't except any format I upload. including PNG, JPG. "Java Script alert"
however, I get about 2 dozen pop ups when I come in from another room to check ujp on this PC and it is "The Process cannot access the file becuase it is being used by another process".

also when It attempts to do read a dll file in GOG Games "cannot access file while trying to rename" I never rename files being installed. and have to abort it. and the reaason I likely misquoted that error message is becase that screen shot I had renamed from PNG to JPG format and then came out blurry I forgot to save the original one.
