When you try to install a patch, you may get the error message "Setup could not verify integrity of file. Make sure the cryptographic service is running." This typically means that the signature catalog has been corrupted. There was a patch to fix this problem, but of course if you haven'
Sometimes you want to perform an activity, such as updating a status window, only as long as the window is not covered by another window. The easiest way to determine this is by not actually trying to determine it. For example, here's how the taskbar clock updates itself:
