I deactivated my current installation, uninstalled and told it to remove everything including settings, rebooted. Installed using the latest 1.4.3_j303build posted here. So far so good. I entered my license key and reactivated, opened the settings. I set the first tab to "Windows 10 style" for the start menu, "Use Start11 Start Menu" option is enabled. Next I clicked on Taskbar on the left side, I enabled the option for "Let Start11 enhance the taskbar" and "Toolbar buttons should be combined..." to "NEVER" option. This is what my screen looks like:
Single screen setup, 3840x12160(recommended) resolution, scaling is set to 150%,. in the windows settings under scaling, (recommended) is next to 250% which just makes everything on my screen huge and unusable, I have tried setting it to 175% 125%, and there is little change, but at this point it's worse than before I re-installed.
