I've been running WB 8.13 for a few months without issue. Nothing on my system has changed, ie. no new hardware etc. since originally installing WB.  Recently I've begun to experience two nasty symptoms which are corrected by unloading WB: 

1)  My browser's interface (GUI) is corrupted, making it impossible to use,

2)  Experiencing random BSODs, with random error messages such as critical_process_error or unknown_error.

When Opera dies, nothing works - even a cold boot, to fix the video corruption. However, as soon as I unload WB, Opera behaves.  Not sure if the blue screen of death is caused by WB as well, but one thing I do know is the two problems started pretty much at thye same time. Tried changing themes within WB, but this did not help.  Here are the important bits:

Win 8.1

AMD 8 Core 4.0MhZ (I do NOT overclock)

8G ram, 3 drives - one SSD + two SATAs

I ran your diagnostic software and have attached the zip to this post.  Please have a look and get back to me.  

Oh, one more thing: although WB is set so that it checks for updates once a week, if there is a higher version I have not seen it. Guess I will have to manually dload and update new versions, but this issue is annoying and should work.  Comments ?

P.S. Seems I can't attach anything to this post, please explain how to get the diagnostic file to you.

Cheers
