I think you should communicate with your colleague as he has already emailed me.

David8888
I don't have any colleagues

I don't have any colleagues who could communicate with you :)
I would highly appreciate if you could share the solution of this problem with me as well.
Thanks !

Are you hacking or copying some other companies product? Because you both are asking the same question with the same issue at the same time?? And you are both from china so its suspicious

David8888
I'm not hacking anything, and

I'm not hacking anything, and I'm from Russia, actually

OK i apologize. Can you do this

Install drmingw https://github.com/jrfonseca/drmingw and then run the DEBUG build of virtualhere

https://www.virtualhere.com/sites/default/files/usbclient/test/vhui64.exe

then when it crashes can you send me the stacktrace that appears in drmingw.

Thanks!

David8888
frankly speaking I'm having

frankly speaking I'm having the problem with crashing the app for quite some time already. initially I was thinking that OS somehow damaged, but after trying it in multiple configurations and different computers, I finally gave and decided to get in touch with you. So there is definitely either coincidence or misunderstanding.

Can you tell me the version(s) of the virtualhere server you are connecting to?

David8888
Actually this situation

Actually this situation happens when I'm not connecting to anything and when the client is looking for the servers.
I'm using the server version 4.0.0

Michael
.

OK i will try to reproduce it here, it seems to be in one of the libraries i use (wxWidgets) so its a tough one to quickly debug... ill let you know if/when i reproduce it. Ill leave it running overnight tonight..

David8888
Many thanks !

Many thanks !

Michael
.

OK i found the bug and (i think) fixed it. Could you try this new 4.9.5 beta build https://www.virtualhere.com/sites/default/files/usbclient/test/vhui64.exe

Let me know if it crashes again and after a few days if its ok.

Ive let it run a while on my test machine and no crashes so far

Michael
.

Actually i decided to push this build to the main download section now...

Many thanks !
Give it a try.
