Greetings,
two little things that annoy me about Classic Shell/Start that I would like to get fixed in a future release:
I am using Classic Shell 4.3.1 on Windows 10 Build 1803.
I can't duplicate that issue on my windows 10 Pro 1803 I have installed Classic Start 4.4.109 https://github.com/passionate-coder/Classic-Start/releases/download/v4.4.109-dev/ClassicStartSetup_4_4_109.exe
Okay, I think I will have to specify my issue a bit further as both issues seem to depend on certain conditions:
Point 1: This only applies to the stock Windows button. Probably you were using a customized version of it when testing?
Point 2: This seems to only be true for certain programs, like Honeyview and MPC-HC, while it works perfectly fine in Chromium for example. In MPV on the other hand, even with the native start menu the task bar does not disappear.
I do not know what causes these differences in behavior but I think if the native menu can make the task bar disappear in these cases, then so can you, right?
Point 1 confirmed

Point 2
Seems I've encountered same issue before, but sometimes even without Classic Shell & Classic Start
Well since you brought up specific programs that I don't have, I retested again with my taskbar set to auto-hide and not to auto-hide. I ran Outlook 2013 full screen. Start button reacts the same. I am using a custom start button Metro Button Size 2.bmp. It stays Blue until I click it our open it with the windows key then it becomes red green blue yellow. on my system full screen still allows the taskbar to be seen unless I have selected to autohide?
Since @MarekWojt opened this issue, has this been resolved/corrected?
It's been almost a year since this has been discussed and it may need to be closed.
