LB Update v13.24 Mouse Input Issue

[neosean99]

After updating Launchbox to the latest 13.24, I noticed that it made mouse clicks almost impossible. Mouse movement is smooth, but left or right clicks are not registered unless clicking about 10 times in one second as if something is causing input lag. I have installed twice to the same problem. Even minimizing Launchbox proceeds to cause the issue while trying to work with other applications. I also noticed while this is occurring I get two Lav filter icons in my taskbar (one red, one white) that disappear if you try to mouse over them. As soon as I close Launchbox, the issue goes away. I have reverted back to 13.23, and can confirm this solves the issue. Before typing this, I updated one more time to 13.24 just to confirm again that this issue is tied to 13.24. 

 

No action necessary for me, I am fine, and will wait for another update. I just wanted to make sure we had this on record in case others experience the same. Thank you community, and devs as always!!!

I also had that same issue with my mouse after updating however, the cursor movement was not smooth as well.  A few moments after closing Launchbox the cursor would return back to normal operation.  So I reverted back to the 13.23 version and its working well again.  I'll just wait for next update to try again.  Can't live without my Launchbox

Only times I've heard something like this reported is when in the Controller options you have "Enable All Controllers" selected. Some machines the scan for controllers seems to take longer than normal and the polling logic causes some systems to lag out the mouse when it's doing so. If you turn that option off I'd assume your mouse would go back to working the way it should. Let us know if that's not the case though.

Thank you very much for the reply C-Beats.  Yes, I did try disabling that option and restarting Launchbox but it made no difference unfortunately.  I also reinstalled 13.24 a few times but for some reason in my setup there must be some sort of conflict or interference somewhere as it keeps occurring.  Not really a problem though as going back to the previous version removed the mouse issue completely.  I'll play around with my settings on 13.24 a bit more, update any drivers if necessary and see if I can find a way to get it to clear up the issue otherwise I'll just hang on till a new version drops.  If I get it working properly I'll post what was wrong in case anyone else experiences it.  You guys are a terrific community and I really appreciate the support and everything I've learned using these forums!  Cheers.

C-Beats I did as well to no luck. I'd also like to note I haven't adjusted those settings in probably 4 years and it was fine until now through all versions (on mine). I had never encountered this issue prior. Revert works.

I just tested this again with 13.25 Beta !. Problem still persists. Still not sure what is causing this one. Dropping back to 13.23 again until another Beta release.

*Edit* It's still an issue, just happens less often.

@C-Beats @____AiR____ I was able to test 13.25 Beta 3, and can confirm it is now solved. Hopefully 13.25 stable will have the solution moving forward.

Nice!  Thanks very much for the heads up neosean99.  I'll definitely update after that version is released. I'm kind of curious what the actual issue was as I never experienced that before but regardless, glad to know its resolved.

I meant to come back and edit what I previously wrote. It is not fixed on Beta... It's just less prominent. After some time of Launchbox or Big Box being open it will happen sometimes still. Tonight I noticed a new one... the mouse cursor dragged up my screen constantly with Launchbox open after the bug kicked in. Took about 15 minutes of being in Launchbox. I was trying to edit some of my VPX tables and it just kind of went haywire. I couldn't get it to stop until I closed LB. Once closed, all was well again. I also encountered a bug on all 3 Beta's where after closing a game BigBox would freeze on returning. Would have to manually close out in Task Manager as closing BB would still leave itself open in Task Manager. I'm starting to get a little frustrated with it as I was excited to get the new screensaver mode running with my VPX tables... and it looks gorgeous, but this is not worth it. I still find it odd that I haven't read too many other reports of this. I can say 100% it's something in LB. I've run this build for 5+ years, and it was not an issue until after 13.23. I've also tested 2 other PC's with different mice / keyboards / and gamepads with the same result.
