LightZone hangs after running for first time

LightZone hangs after running for first time


Just installed LZ vz. 4.1.8-20171226-amd64 on my Windows !0 pc.  It appears to install fine and initially opens fine.  It will let me choose the picture folder but when I go to select a picture and edit it the app just hangs and locks up. 

Here is error message in Event Viewer.

The program LightZone.exe version stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel.

Any suggestions?  Thanks.

Did you check

your security software, whatever you have installed, and the SmartScreen thingy?

And, what kind of a picture did you try to edit?

Have a nice day!

My anti-virus progam is

My anti-virus progam is windows Defender.  As for the looks like I don't even have that enabled.  All the googling I did on it says there should be an option from the Control Panel>>System and Security>> Security and Maintenance panel and there is none.  So I believe it is already disabled.

  I was trying to edit a .jpg file. 

I added LightZone as an approved  app in the firewall settings and I run LightZone as an admin.  It still locks up on me.

Thank you.

On macOS it hangs!

Here I'm on macOS HS (10.13): as the first user in this thread said, my LZ starts fine but when I try to open a file (jpg) it hangs forever !

Any update for macOS? I'm running the latest available version 4.1.8 just downloaded from web site.
