I run Tixati portable 32 bit on Windows 10 1809 32 bit.
When I click on Tixati notification in the right corner of taskbar, even after closing Tixati other notifications from Windows 10 (e. g. when connecting a flash drive) can no longer slide out from right until I sign out and sign in to Windows again.
If I leave notification from Tixati untouched then after closing Tixati notification disappears and nothing is broken.
