I'll try and make this as concise as possible, understanding that more will be required as we get into the troubleshooting.
Here are the basics:
Machine is a Lenovo Y50-70 Touch. Core i7 @2.6 GHZ with Nvidia GEForce GTX graphics card. 64 bit, Win10 Home edition (fresh load).
Application in question is MultiPub client (tiny application). Who cares one way or the other, except that it works completely 100% fine on multiple other machines in the office, including all of my virtual machines. So, hard to point a finger at the installation itself.
Here's the order of effects:
1. Double click the application, login screen pops up. So far, so good.
2. Enter username - as per normal in any other app. Still good.
3. Tab / Click down to password text box right below - application hangs right here, and I only know it doesn't freeze because I've waited the damn thing out and eventually it will give you a cursor in the password box. But, for all intents and purposes, once you hit password box, the app is toast.
4. If you wait it out, and enter your password and click Submit, the application will load as it should, although it seems to work at about 25% speed - extremely slowly, so as to be unusable.
I have thrown the book at this thing - ever troubleshooting item I could think of with the help of Google, I've thrown. The BIOS is updated. I've checked every Win10 setting I can think of. I've turned off the graphics card, booted in safe mode, etc, etc, etc, etc. I need someone to help me take a fresh look at this thing. The computer seems completely functional and normal outside of this oddity, which makes it effectively useless for my office.
Throw me a bone, folks, and lend me your brain for a moment.
Cheers and Thanks,
