Hello all, Nikolay, thank you for posting this problem that you are seeing. I get the same problem when I use this timer in my code and I have no idea what could be the issue... If anyone know the reason why or how to improve it, I would greatly appreciate the answer as well..... The followinig are some questions that come into my mind: 1. Is there some more occurate timer out there? 2. Could this potentially be because there are many other applications runnign in the background? 3. Is there someway to turn off those applications? NOTE: I posted questions 2 and 3 in my earlier post and didn't get a responses...
Thank you again for all of your help and I greatly appreciate your response.
