Application lost focus

  • Problem
  • Updated 12 months ago
  • Solved
Hello. I'm trying to run 3D Mark but when I do, it crashes with the error "Application lost focus or display resolution failed. Close all background applications." This happens right after the program launches or just a little ways into the Jane Nash test

I have no other applications running. One time when I ran it, right before program launched, in my task bar I saw the message, "Windows has changed to basic setting . . ." something about the program running didn't support my current display settings.

I've looked around the support site and one solution was to select the "Keep current settings and don't ask again" window that pops up under these circumstances, but I don't get that window and therefore can't choose that option.

Thanks for any help.

Could you describe your hardware configuration and operating system version.

Also I would still like to know what you have running in the background. A screenshot of processes from the task manager would be useful.

For some reason the problem stopped altogether, which is slightly disconcerting considering I've not done anything or changed anything other than a reboot (which hadn't solved the problem before). If it crops up again I'll send over my specs and a screenshot. Thanks for the reply.

Hello,

My issue has returned. I'm attaching a screenshot of the processes that you requested. As before, the only application I'm running is the benchmark.

My system is:

Windows 7
Intel i-5 3740
Gigabyte H77-DS3h Mobo
Gigabyte GTX 660 GPU
Crucial 8 Gig RAM
Gigabyte 720 Watt PS

Thanks.

Almost certainly caused by TWCU.exe

I googled up what this process is and found this;

http://forum.tp-link.com/showthread.p...

" I bought a TP-Link TL-WN821N wireless adapter and since I installed it I have had problems with programs changing focus by themselves. I come to the conclusion that it's the process TWCU.exe that causes this. If I cancel this process the problem dissapears. While googling about this, I've also noticed that other people are having the same problem with this process."

Apparently this application isn't required for using this wireless adapter - you can also just rely on built-in Windows wireless config tool instead.
