This just started about 2 days ago. I use the latest release of Firestorm. What happens is, I log in, and the whole viewer starts flickering black screen, then normal...repeatedly. And at the top when it goes black it says Not Responding. Then back to normal. Like every 2 seconds or so it does this. Also, What I have observed is the SL icon on the taskbar on Windows 8.1, continually jumps across the taskbar. Has anyone else experienced this? And if so...how do I fix it?? Here is what I've done so far: Clean install, tried a different viewer, did a Refresh on my PC, updated all the windows updates, and graphic card update. Re-installed Firestorm, and Singularity...both still do this. Am I going to have to completely re-install windows?? I need some advice please. This is a new Laptop I've had since March, and it runs SL GREAT. No problems til now. Please help! Idk what info you need about my PC but here is what I have OS: Windows 8.1 Acer Aspire V 15 V3-572G-51DR Intel Core i5-5200U NVIDIA GeForce 840M with 2GB dedicated VRAM 8GB DDR3 L Memory 500 GB HDD Thank you.
