  • Can we please stop sharing these porn stories every week? We get it, there is VR porn.
  • wrong article man. Just a heads up.
  • I agree. I'm always getting these porn headlines on my app widgets and then friends and kids go on my phone.
  • I know! I'm going to church (I have a bible app on my phone) and these porn things pop up
  • I think it's advertising in the first place.
    Cause "VR Heads" site belongs to mobile nations too.
    And it's bad advertising in my opinion.
  • Agreed, not interested in any of that dirty sh*t, no need to be resurfacing it everyday like it's the only news worthy thing about vr...
  • Here's what's new....nothing new :-P In all seriousness though sounds like a lot of good fixes in there.
  • this is for the PC, mobile is dead anyways
  • Facepalm
  • Since I've installed it on the L830, I've only noticed more bugs... The way feedback looks, I'm not the only one finding them as well.
  • I'll have to go peek at the feedback. What are you seeing? I am not seeing anything odd stand out.
  • If I remember right, adding photos to text messages, and the saving message when taking a photo seems to be popping up more.
  • Really have not seen any have you tried a soft reset
  • o yea. The "saving" message can only be fixed by a soft reset.
  • That sucks, not seeing that issue on my XL.
  • My cat finally learned how to use the door.
  • Mine tries like heck. He reaches for it, but that whole thumb thing is messing him up.
  • If cats had opposable thumbs we'd all be their slaves by now
  • Mine learned how to locate and assault ghosts only he can see, and he does it every morning around 4 AM.
  • That sounds like something strange, in your neighbourhood. Who you gunna call?
  • Nothing in there to indicate what caused the problem I had on Wednesday. I had to replace a system file with the old version to make my PC work properly again
  • Installed it on my xl. No complaints
  • Are there Insider ring updates that are not cumulative? I don't think so. So why not leave the term "cumulative update" for Production updates?
  • I don't think what you said made any sense.
  • I'm still waiting for the build that was supposed to be released yesterday. Or am I wrong?
  • If you are talking about the Fast Ring, they did release a build.
  • We fixed issues with Internet Explorer, Xbox, Internet Explorer again, Skype, SMS messaging, Internet Explorer, your mom, a potato, some dude we found, Internet Explorer, a particularly angry cat, FILE Explorer, internet explorer..., Internet Explorer again, and Jesus.
  • In all seriousness I'm just waiting for my precious 950 XL to return from the shop to get this Build. My 950 is a Fast Ring baby.
  • Yeah, IE11 has been available on the market for over 3 years now. I know it's available on 3 OS versions, but neither do I understand why there are so many bugs with it.
  • What about MS Edge ? Why MS is not improving it's stability ? Its my primary browser in office and home pc... Where i get alert for mails Edge use to go non responsive for few mins. Can't handle many tabs, some times pages not load at all....
    Drag n drop a link to new tab still doesn't work yet.....
  • Latest update now refuses to run Plex Media Server. Not sure if alone or someone else got this bug.
  • Not that one but it's interesting that a media player app is causing you problems. My issues were around PowerDVD 16 (the media server crashed constantly - are we seeing a correlation here?), Windows Media Player crashed when attempting to play .mpg files and any folder containing these files crashed dllhost (COM Surrogate). All these errors were caused by an updated system file 'CompPkgSup.dll' which was included with the update (it's dated January 13). I replaced the file with the older version (16 July) from my image backup and everything worked again. If you can, try that. You need to take ownership of the files (they're in system32 and also SysWow64 if you have 64-bit OS), and copy them from your backup. Be interesting if that solves your problem - I think there's a codec that isn't playing ball with this new file.
