Have you tried storing the location (x, y) and width and height of the the alert component when it pops up? And tried restoring those values when your window is restored back on screen?
Thanks for the suggestion, however the issue occurs when the popup is created while the window is minimized, so the initial location and height are never set to the correct values and thus storing them will not help
I am also experiencing the same problem in Alert box.
The below link is not working? Do you have any idea -How to check status of below bug?
Also in addition, Did you find any workaroud or solution for this problem?
