I have some Spark issues with the display.
On several users (nothing I can find in common), and even on my machine on occasion, it’s like Spark has display issues. If Spark is actually minimized down into the taskbar, it isn’t redrawn to be gone- the window remains.
Similar problems occur over all of the screen- other windows won’t close.
If I do a Windows+D (show the Desktop), which forces the screen to be redrawn as the desktop, it goes back to normal. However my issue is that the common user doesn’t know this.
Is this a reported bug, or something known?
